🇲🇵 Northern Mariana Islands at a Glance
🌍 Overview — Fourteen Islands, Three That Matter
The Commonwealth of the Northern Mariana Islands is a chain of fourteen volcanic and limestone islands running roughly 600 km north to south in the western Pacific, about 2 400 km east of Manila and 2 600 km south of Tokyo. Total land area is 464 km² and the population is around 47 000. Almost everyone lives on three southern islands — Saipan, Tinian and Rota — and the eleven to the north are essentially empty.
Everyone born here is a United States citizen. The islands use the dollar, the postal service is USPS, the courts are federal, and the passport is American. They are not a state, they have no vote for president, and their single delegate in Congress cannot vote on the floor. This page spends a good deal of time on that arrangement because it explains nearly everything else.
⚠️ Read this first
On 14 April 2026 Super Typhoon Sinlaku struck Saipan and Tinian at Category 4 and intensified to Category 5. Recovery is well advanced but not finished, and the practical situation on the ground is still not normal. See Typhoon Sinlaku before you plan anything.
What people come for
Wreck and cave diving that is genuinely world class, the most concentrated Pacific War battlefield you can walk across, beaches on a lagoon that is one of the largest in Micronesia, and — for those who go looking — a living Chamorro culture that survived four colonial administrations.
What surprises people
How American it is and how completely not American it feels. Fiesta culture, betel nut, Chamorro and Carolinian spoken in the street, Filipino and Chinese communities, Korean and Japanese signage — under a US flag, with a US post office and a US minimum wage.
⭐ The one-line summary
An American territory, in a Micronesian culture, with a Japanese colonial past, a Spanish colonial name, a Pacific War memory that dominates everything, a Chinese and Korean tourist economy that keeps collapsing, and the deepest hole in the ocean immediately offshore.
🇺🇸 What a Commonwealth Actually Is
The Northern Marianas are the only place on earth whose people voted to become American and got it. That is a genuinely unusual origin and it shapes the whole relationship.
How it happened
After 1945 the islands were administered by the United States as part of the Trust Territory of the Pacific Islands, a United Nations strategic trusteeship. When the Trust Territory broke up in the 1970s, the other districts went for independence or free association — the Marshall Islands, Palau, the Federated States of Micronesia. The Northern Marianas went the other way. In a 1975 plebiscite, 78.8 % voted to approve a Covenant establishing political union with the United States. The Commonwealth government took effect in 1978, the trusteeship formally ended in 1986, and US citizenship was conferred the same year.
What the Covenant gives
US citizenship by birth. The dollar, USPS, federal courts, federal disaster relief. Local self-government with an elected governor and a bicameral legislature. Control — originally — over immigration, minimum wage and customs, which no state has.
⚠️ What it does not give
No vote for President. One non-voting delegate in the House of Representatives, currently Kimberlyn King-Hinds, who may speak and sit on committees but cannot vote on the floor. No senators. Federal laws apply whether or not anyone here was consulted.
What Washington took back
Immigration control was federalised in 2009 under the CNRA, ending the Commonwealth's own guest-worker and visa regime. The local minimum wage was put on a federal escalator from 2007. Both were responses to the garment industry (see below) and both were deeply resented as unilateral rewriting of the Covenant.
The governor
David M. Apatang, who became governor on 24 July 2025 after the death in office of Governor Arnold I. Palacios, who collapsed in his office on Capitol Hill and died the previous evening, aged 69. Senate President Dennis Mendiola became lieutenant governor.
Guam next door
Guam is the southernmost Mariana island and is not part of the Commonwealth — it is a separate unincorporated US territory, has been American since 1898, and is much larger, busier and more militarised. Same island chain, same Chamorro people, two different colonial timelines. Locals will correct you on this and they are right to.
⭐ Why it matters to you
Practically, an American entry regime (see Practical), American prices, American infrastructure standards — and an economy with none of the fiscal capacity of a state, which is why a single typhoon can knock it flat.
🗺️ A Double Arc of Islands
The Marianas are a volcanic island arc, produced where the Pacific Plate dives beneath the Philippine Sea Plate. The geology splits them cleanly in two, and the split is the single most useful fact for understanding the place.
⭐ The southern islands
Saipan, Tinian, Aguiguan, Rota — and Guam, outside the Commonwealth. These are old volcanoes capped and buried in uplifted coral limestone. They are relatively flat-topped, they have caves, sinkholes, wave-cut notches and freshwater lenses, and they have the beaches. All the people, all the agriculture and all the tourism are here.
The northern islands
Anatahan, Sarigan, Guguan, Alamagan, Pagan, Agrihan, Asuncion, Maug, Farallon de Pajaros and others — young, steep, active stratovolcanoes, almost all now uninhabited. Agrihan reaches 965 m, the highest point in the Commonwealth. Anatahan erupted violently in 2003 after no recorded historical activity, and Pagan has erupted repeatedly.
Saipan
The main island: 115 km², around 43 000 people, a long western lagoon sheltered by a barrier reef, a spine of limestone hills rising to Mount Tapochau, 474 m, and cliffed windward coasts in the north and east. Garapan is the tourist town; Capitol Hill is the seat of government.
Tinian
101 km², around 2 000 people, flat, and covered in the tarmac of the largest airfield built anywhere during the Second World War. A third of the island is leased to the US military. The Taga latte stones are here and so is North Field.
Rota
85 km², around 2 000 people, the quietest and the greenest, with the best surviving forest and the best birdlife in the archipelago. It escaped the 1944 fighting almost entirely, which is why. If you want the Marianas before tourism, this is it.
Climate
Tropical marine, hot and humid all year — 27–30 °C essentially always. Dry season December to June, wet season July to November, which is also typhoon season. The trade winds blow from the east almost continuously and are the reason the western lagoon exists as a usable anchorage.
🌊 The Mariana Trench
Immediately east of these islands the seafloor falls away into the Mariana Trench, and at its southern end lies Challenger Deep, at approximately 10 935 metres the deepest known point in any ocean. Everest, inverted and dropped in, would leave more than two kilometres of water above its summit.
How it works
The Pacific Plate is the oldest, coldest and densest oceanic crust on earth, and here it is subducting beneath the Philippine Sea Plate at a steep angle with almost nothing pushing back. That combination — old dense slab, no continental buttress — is why this trench and not another is the deepest.
Who has been down
1960: Jacques Piccard and Don Walsh in the bathyscaphe Trieste. 2012: James Cameron, solo, in Deepsea Challenger. 2019 onwards: Victor Vescovo's Limiting Factor, repeatedly, including with Walsh's son and with Kathy Sullivan, the first woman to reach it. More people have walked on the Moon than have been to the bottom of Challenger Deep.
⚠️ What they found there
Amphipods, xenophyophores, microbial mats — and a plastic bag, along with detectable concentrations of PCBs in the fauna. The deepest place on the planet is not clean. It is one of the bleaker facts in modern oceanography and it was established here.
The Monument
The Marianas Trench Marine National Monument was proclaimed in 2009 and covers about 246 000 km² in three units: the trench itself, the volcanic arc with its hydrothermal vents and mud volcanoes, and the waters around the three northernmost islands. It protects one of the strangest set of habitats anywhere, including a lake of liquid sulphur and vents emitting molten sulphur.
What you can see
Nothing, directly. No submersible tourism operates here and the trench is invisible from land. What you can do is stand on the eastern cliffs of Saipan and know that the seabed forty kilometres out is deeper below sea level than any aircraft you have flown in was above it.
Earthquakes
The subduction zone produces frequent earthquakes, most of them unfelt. Damaging ones are rarer here than in Japan because the plate interface is largely uncoupled — the slab slides rather than sticking — which is also part of why the trench is so deep.
🌀 Super Typhoon Sinlaku, April 2026
This section is the most important practical information on this page and it will date. Check current conditions before you book anything.
On 14 April 2026 Super Typhoon Sinlaku made landfall on the Northern Marianas as a Category 4 storm with sustained winds around 150 mph (240 km/h), intensifying to Category 5 and roughly 175 mph. Saipan and Tinian took the core. More than 500 mm (20 inches) of rain fell. Power went out island-wide, roofs came off, roads were blocked and communities flooded. The storm is associated with around 17 deaths and damage estimated at over US$1.55 billion across the affected area.
For a Commonwealth with a total population of 47 000 and an annual budget a fraction of that damage figure, this is not a weather event. It is a restructuring.
Where recovery stands
⚡ Power and water
By late spring, roughly 98 % of primary power lines had been re-energised and Saipan's water production was back to about 92 % of capacity, with around 98 % of customers on 24-hour water. Utilities are broadly restored; localised outages have continued.
✈️ Flights
Saipan International reopened progressively and has been operating daytime flights only. Jeju Air resumed Seoul Incheon on 20 June 2026; United restored Tokyo Narita on 2 August 2026; Hong Kong Airlines returned over the summer and Philippine Airlines was expected back in October 2026. Verify your specific routing — this is still moving.
🏨 Hotels
Reopening property by property. Aqua Resort Club, Crowne Plaza Resort Saipan, Kensington Hotel Saipan, Pacific Islands Club Saipan and Surfrider Resort have been restoring services, with room availability and amenities varying. Book directly and ask what is actually working — pools, restaurants and air conditioning have not all come back at once.
⚠️ What to expect
Debris piles, blue tarpaulins on roofs, closed businesses, reduced restaurant hours, damaged trails and beach facilities, and vegetation that was stripped and is regrowing. Dive operators and war sites have reopened unevenly. None of this makes a visit a bad idea; it makes an unprepared visit a frustrating one.
And this was the second one
In October 2018, Super Typhoon Yutu crossed Tinian and southern Saipan as a Category 5 with gusts over 290 km/h — at the time the strongest storm ever recorded to strike any part of the United States. It destroyed a large share of Tinian's housing stock. The islands had not fully recovered from Yutu when the pandemic closed the tourist market, and had not recovered from the pandemic when Sinlaku arrived.
Three compounding disasters in eight years, on an economy where tourism is more than two thirds of GDP, is the actual story of the contemporary Northern Marianas, and no amount of brochure language about Pacific paradise should obscure it.
🌿 Reefs, Forests and the Snake That Has Not Arrived
The reef
Saipan's western lagoon is one of the larger lagoons in Micronesia, enclosed by a barrier reef from Managaha down to the southern tip. Coral cover has been hit repeatedly by bleaching and by storm damage; the fish life remains good and the water clarity outside the lagoon is exceptional. See Diving.
⭐ The birds
The Marianas have endemic birds found nowhere else: the Mariana fruit dove (Ptilinopus roseicapilla), the golden white-eye and bridled white-eye, the Micronesian megapode, the Rota white-eye — critically endangered and confined to one forest on one island — and the Mariana crow (åga), which is functionally extinct on Guam and survives only on Rota.
⚠️ The brown tree snake
Boiga irregularis arrived on Guam in cargo after 1945 and ate that island's forest birds to extinction — nine of twelve native species gone. The Northern Marianas have so far kept it out. Cargo and aircraft are inspected, detector dogs work the ports, and any snake sighting is treated as an emergency. It is the single most important conservation fact in these islands and it depends entirely on biosecurity holding.
Coconut crabs
Birgus latro, the largest land arthropod on earth, lives here and is eaten here. Populations are under pressure from harvesting and from habitat loss. If they are on a menu, they were probably taken legally; whether they should be is a separate question and locals disagree about it.
Forest
The best surviving native limestone forest is on Rota, with Tinian and Saipan far more disturbed — first by Japanese sugar cane, which cleared most of Saipan, then by war, then by development. The Sabana on Rota and Talakhaya are the places to see what the islands looked like.
Marine life
Green and hawksbill turtles nest on the beaches and are federally protected — do not approach nests. Spinner dolphins are common. Sharks are present and unproblematic. Manta rays turn up at Rota. Whale sharks and whales pass through seasonally and reliably surprise everybody.
🪨 The Chamorros and the Latte Stones
People reached the Marianas from island Southeast Asia around 1500 BC — one of the earliest long-distance open-ocean crossings anywhere, and the first human settlement of remote Oceania. The people who made it are the Chamorros (CHamoru), and they are still here.
The latte
From around 900 AD until Spanish contact, Chamorro builders raised houses on paired rows of stone pillars. Each is a haligi — a tapering shaft of coral limestone or basalt — topped with a tasa, a hemispherical capstone set curved-side up. Nothing quite like it exists anywhere else in the Pacific, and the form is now the emblem of Chamorro identity across the whole archipelago: on flags, on seals, on tattoos, at the entrance to villages.
The largest are at the House of Taga on Tinian, where the shafts stand around five metres and are estimated at more than 30 tonnes apiece. One remains upright; the rest were felled by earthquakes. Quarrying, moving and raising them without metal tools or draught animals was an engineering achievement that is still not fully explained.
What they were for
House supports, raising the floor above ground for ventilation and to keep out rats and damp. The bigger ones probably marked high status. They were not temples or tombs, though burials are frequently found beneath them.
The society
Matrilineal — property, land rights and clan identity passed through the mother's line, and the practice survives socially even now. A ranked society with chiefly lineages (chamorri), skilled in open-ocean navigation, fishing, rice cultivation (unique in the pre-contact Pacific) and pottery.
⭐ The sakman
The Chamorro flying proa — a single-outrigger sailing canoe with an asymmetric hull that was faster than any European vessel of its era. Anson's men in 1742 measured one at what they reckoned to be around twenty knots. Magellan's crew were genuinely astonished. Modern replicas have been built and sail out of Saipan and Guam.
Where to see it
House of Taga, Tinian. The latte quarry at As Nieves on Rota, where half-finished pillars still lie in the rock — the single most eloquent archaeological site in the islands. Latte sets on Saipan, and the collections in the NMI Museum of History and Culture in Garapan.
The name
CHamoru is now the preferred spelling, adopted officially in 2018 with a capital CH to reflect the language's own orthography. Chamorro remains in wide use, including in US federal documents. Both are used here; neither is an insult.
⚠️ Do not climb them
This should not need saying and does. Latte are ancestral property, they are structurally fragile after a thousand years, and standing on one for a photograph is exactly as welcome as it would be on a gravestone.
⛪ Spain, 1521–1899 — Contact and Collapse
Magellan made landfall in the southern Marianas on 6 March 1521, the first European contact with any Pacific island people. It went badly within hours. Chamorros came aboard and took things — in a gift-exchange culture where taking was an overture, not a theft — and Magellan's men burned a village and killed several people in reprisal. He named the archipelago Islas de los Ladrones, the Islands of Thieves, and sailed on. It is one of the more consequential cultural misunderstandings in history and the name stuck for a century and a half.
Spain formally claimed the islands in 1565 but did nothing with them beyond using Guam as a watering stop for the Manila galleon, which crossed the Pacific twice a year for 250 years. Missionary settlement began in 1668, when the Jesuit Diego Luis de San Vitores arrived and renamed the archipelago Las Marianas after Queen Mariana of Austria, his patron.
⚠️ What followed
The Chamorro–Spanish Wars ran from 1670 to 1698. They were not a conquest of armies; they were a long series of revolts, reprisals and village burnings. What did the killing was disease — smallpox, influenza and the rest, arriving in a population with no immunity at all.
Estimates of the pre-contact Chamorro population vary widely, commonly from 40 000 to well over 50 000. By around 1700 there were roughly 4 000 left. The survivors were then subjected to the reducción: forcibly concentrated into a handful of mission villages on Guam and Rota, with the northern islands emptied entirely. It is one of the steepest demographic collapses recorded anywhere, and it is the reason the modern Northern Marianas were substantially repopulated from elsewhere.
The Carolinians
In the early nineteenth century, people from the Caroline Islands — Satawal, Elato, Lamotrek and the other atolls — began settling Saipan, a movement accelerated by a catastrophic typhoon in 1815 that devastated their home islands. Spain permitted it. Their descendants are the Refaluwasch (Carolinians), a distinct people with their own language and their own place in the Commonwealth's constitution.
What survived
The language, the matrilineal clan structure, the fishing knowledge, and a great deal of practice absorbed into Catholic form. Chamorro culture is not a reconstruction; it is a continuity that was very nearly severed and was not.
Catholicism
Overwhelming and genuine. Every village has a patron saint and a fiesta; the church calendar is the social calendar. San Vitores was killed in 1672 on Guam by the chief Mata'pang after baptising his daughter without consent — and was beatified in 1985, which remains a sore subject.
1899
Spain lost Guam and the Philippines to the United States in 1898. With no way to hold what remained, it sold the Northern Marianas, the Carolines and Palau to Germany in 1899 for 25 million pesetas. This is the accident that split one island chain into two jurisdictions — and it has not been repaired since.
🇩🇪 The German Interval, 1899–1914
Germany held the Northern Marianas for fifteen years, administering them from Yap as part of German New Guinea. It is the shortest and quietest of the four colonial administrations and it left the least behind.
What they did
Copra. Coconut plantations were the point, and a modest administrative apparatus was set up on Saipan to run them. A district officer, a handful of German officials, and the Capuchin mission — which took over from the Spanish Jesuits and left a lasting mark on the church here.
What they left
Very little physical trace. The German cemetery on Saipan, some plantation boundaries, a few surnames, and the Capuchin presence. No fortifications and no infrastructure of consequence — the islands were an afterthought in a colonial empire that was itself an afterthought.
How it ended
In October 1914, weeks into the First World War, a Japanese naval squadron arrived and took the islands without a fight. Germany had no fleet in the Pacific capable of contesting it. The transfer was formalised as the South Seas Mandate under the League of Nations in 1920.
⭐ Why the interval matters
Because it broke the continuity. For two centuries the Marianas had been a single Spanish administrative unit. After 1899 Guam went one way — American, then and since — and the north went German, then Japanese, then American. The Chamorro people were partitioned by a sale, and the cultural and political divergence dates from exactly here.
🇯🇵 The Japanese Era, 1914–1944 — Sugar and Settlement
The thirty Japanese years transformed these islands more thoroughly than the two Spanish centuries. If you want to understand why Saipan looks and functions as it does, this is the period that did it.
Nan'yō
Japan administered the islands as the Nan'yō-chō, the South Seas Government, headquartered on Palau. Saipan became the economic centre of the whole mandate, and the engine was sugar. The South Seas Development Company (Nan'yō Kōhatsu), driven by Matsue Haruji — universally known as the Sugar King — cleared most of the island for cane, laid a narrow-gauge railway around it, and built a mill at Chalan Kanoa.
Settlers followed in numbers that are hard to overstate. By the late 1930s Japanese, Okinawan and Korean residents outnumbered Chamorros and Carolinians by something like five or six to one on Saipan. Garapan was a Japanese town of some 15 000 people with a main street, shops, schools, a hospital, shrines and a brothel district. The indigenous population was a minority in its own islands.
What was built
The sugar railway, the Chalan Kanoa mill, Garapan town, the harbour works, roads, an airfield at Aslito on Saipan and the beginnings of Ushi Point on Tinian, a hospital, a jail — and the Japanese school system, which taught in Japanese and which many older Chamorros attended.
What remains
Far more than you expect. Sugar King Park in Garapan with Matsue's statue and a locomotive. The Old Japanese Jail, where Amelia Earhart was supposedly held — she was not, and the story is addressed in the war sites section. Shinto shrine remnants, the sugar dock, concrete foundations everywhere in the bush.
⚠️ Militarisation
From the mid-1930s Japan fortified the mandate in breach of the League terms, and after 1941 the Marianas became the inner defensive ring of the empire. By 1944 Saipan and Tinian held tens of thousands of troops and a civilian population that had nowhere to go.
How it is remembered
Complicatedly. Older Chamorros who grew up under the Japanese describe an administration that was orderly, developmental and thoroughly racist, in which they ranked third — below Japanese and Okinawans. And then it ended in the worst month in these islands' history.
⚔️ The Battle of Saipan, June–July 1944
On 15 June 1944 two US Marine divisions landed on the western beaches of Saipan. Twenty-five days later the island was declared secure. What happened in between killed most of a Japanese garrison of around 29 000, some 3 000 Americans with over 10 000 wounded, and a still-disputed number of civilians running into the thousands.
The landing
Around 71 000 US troops went ashore across beaches south of Garapan under heavy artillery fire pre-registered on the reef line. The first day cost some 2 000 casualties. The Japanese commander, Lieutenant General Yoshitsugu Saitō, fought a defence in depth from the limestone ridges inland rather than at the water's edge.
Offshore
The invasion drew out the Japanese fleet and produced the Battle of the Philippine Sea on 19–20 June — the Great Marianas Turkey Shoot — in which Japanese naval aviation was destroyed as an effective force, losing roughly 600 aircraft and three carriers. After it there was no relief coming and the garrison knew it.
⚠️ 7 July: the banzai charge
With his command collapsing, Saitō ordered a final attack and then killed himself, as did Vice Admiral Chūichi Nagumo — the man who had commanded the carriers at Pearl Harbor. Around 4 000 men, including wounded on crutches, charged the American lines at Tanapag before dawn. It was the largest banzai attack of the Pacific War, it overran two Army battalions, and it was annihilated.
⚠️⚠️ Marpi Point
In the final days, civilians — Japanese settlers, Okinawans and Koreans, and some Chamorros — went to the northern cliffs and jumped, or were killed by soldiers, or by their own families. Japanese propaganda had told them the Americans would torture and rape them. US interpreters with loudspeakers tried to talk them down from boats offshore. The sites are now called Banzai Cliff (Puntan Sabaneta) and Suicide Cliff (Laderan Banadero). Estimates of the dead run to around a thousand, and no figure is reliable.
What it changed
Saipan put Japan's home islands within B-29 range. The Tōjō cabinet fell on 18 July 1944, nine days after the island was declared secure. Everything in the last year of the Pacific War — the firebombing of Tokyo, and ultimately the atomic missions from Tinian — followed from these twenty-five days.
⭐ Captain Ōba
Captain Sakae Ōba led around 46 soldiers and several hundred civilians in the hills of Saipan for 512 days after the island fell, evading repeated sweeps. He surrendered formally, with his men in ranks, on 1 December 1945 — three months after Japan's surrender — only when shown written orders from his former commanding officer. The Americans nicknamed him the Fox.
One thing is worth saying plainly to anyone visiting these sites. For the Chamorro and Carolinian population, 1944 was not a liberation from an enemy — it was a battle between two foreign powers fought across their homes, in which they were bombarded by one side and used as labour and human shields by the other. They lost their villages, their land and a great many of their people, and then spent decades getting the land back from the US military. Nobody asked them.
☢️ Tinian and North Field
Tinian was taken between 24 July and 1 August 1944 in an operation still taught as a model: a feint at the obvious beaches near Tinian Town, and a real landing across two absurdly narrow strips of coast at the northern White Beaches, where the Japanese had not thought a landing physically possible. American casualties were a fraction of Saipan's.
Then the Seabees went to work, and within months Tinian held the largest airfield in the world.
North Field
Four parallel runways, each about 2 600 metres, plus hardstands, taxiways and a road grid laid out and named after Manhattan — Broadway, Eighth Avenue, 42nd Street — because the island's outline reminded somebody of the shape of Manhattan. From here the XXI Bomber Command flew B-29s against Japan. At its peak the field handled a scale of operations that has not been matched by any airfield since.
⚠️ 6 and 9 August 1945
The 509th Composite Group was based at North Field. On 6 August 1945 the B-29 Enola Gay took off from Runway A for Hiroshima. On 9 August Bockscar took off for Kokura and, finding it obscured, bombed Nagasaki. Both aircraft were loaded from pits dug into the coral.
The atomic bomb pits
Pit No. 1 and Pit No. 2 are still there, preserved and covered with glass, with interpretive panels. They are small, shallow, unremarkable rectangles in the ground on a quiet, overgrown island where nothing much happens. That disproportion — between what they look like and what came out of them — is the whole experience, and there is no monument anywhere that does it better by doing less.
What else survives
Kilometres of intact runway and taxiway, now cracked and grown over with tangantangan scrub; the air operations building; Japanese command posts and communication bunkers from 1944; and the Manhattan street grid, still signposted. You can drive most of it. Take water — there is no shade and no shop.
⭐ The House of Taga
Also on Tinian, and a deliberate pairing worth making. A thousand-year-old Chamorro monument a short drive from the place the atomic age took off. If you go to Tinian for one thing, go for both of these in the same afternoon.
Tinian today
Around 2 000 people, one small town, a ferry and a short flight from Saipan. Battered by Typhoon Yutu in 2018 and again by Sinlaku in 2026. Roughly two thirds of the island is leased to the US military under the 1975 Covenant, and the buildup is bringing North Field back into use.
How to treat it
Quietly. These are not adventure sites. Japanese families come to Saipan and Tinian to remember their dead, American veterans' descendants come for theirs, and Chamorro families lost people here too. There is no version of this ground that belongs to only one story.
🕊️ The Trust Territory, 1947–1978
After the war the Northern Marianas passed to the United States as part of the Trust Territory of the Pacific Islands — a strategic trusteeship under the United Nations, the only one ever created, which meant it answered to the Security Council rather than the General Assembly and that the administering power held a veto over its own oversight.
⚠️ The closed years
From 1953 to 1962 Saipan was effectively shut. The CIA ran a training facility at Marpi — the Naval Technical Training Unit — preparing Chinese Nationalist personnel for operations against the mainland. The island was closed to outside visitors, including to other parts of the Trust Territory, and the Commonwealth's own people needed permits to move around.
Land
The US military held vast tracts taken during and after the fighting, including most of Tinian. Returning land to Chamorro and Carolinian families took decades of litigation and political pressure and is still not wholly finished. It is the deepest grievance in local politics and predates every other one.
Why they chose union
When the Trust Territory broke up, the Northern Marianas had watched the alternatives and wanted none of them. They had thirty years of American money and American administration, a tiny population, no resources, and a vivid memory of what happens to islands nobody protects. Union offered citizenship, the dollar and a defence guarantee. The other districts wanted sovereignty; these islands wanted security.
⭐ The 1975 vote
78.8 % yes. It was not close and it was not coerced, and Commonwealth politicians have invoked it ever since — usually when arguing that Washington has not kept its half of the bargain.
🧵 The Garment Industry — Made in USA
For about fifteen years the Northern Marianas ran one of the strangest economic arrangements in the American system, and it ended in a federal corruption scandal that reached the Republican leadership of the House of Representatives.
The loophole
The 1975 Covenant left the Commonwealth in control of its own immigration and its own minimum wage, while granting its products duty-free, quota-free access to the United States and the right to the label “Made in USA”. Somebody noticed. From the mid-1980s, garment factories — overwhelmingly Chinese and Korean owned — opened on Saipan, importing tens of thousands of workers from China, the Philippines, Bangladesh and Sri Lanka on local permits.
At its peak the industry employed something over 15 000 foreign workers, exported on the order of a billion dollars a year, and made the Commonwealth's factory workforce larger than its citizen population.
⚠️ The conditions
Recruitment fees of thousands of dollars that indentured workers before they arrived. Contracts waiving the right to join a union, to attend church, to marry, to become pregnant. Barracks housing behind fences. Confiscated passports. Wage rates a fraction of the mainland minimum. Federal investigations, class actions and a US$20 million settlement in 2003 followed.
⚠️ Abramoff
The lobbyist Jack Abramoff was retained to defend the arrangement in Washington and did so with conspicuous success for years, organising sponsored trips for congressmen and their staff — including for Tom DeLay, then House Majority Whip, who described Saipan as “a perfect petri dish of capitalism.” Abramoff went to federal prison in 2006 on unrelated fraud and conspiracy charges. The Marianas work is a substantial part of the record.
How it ended
Three things at once. The WTO Multi-Fibre Arrangement expired in 2005, ending the quota advantage. Congress put the local minimum wage on a federal escalator in 2007. And the 2008 CNRA federalised immigration from 2009. The last factory closed in 2009. Nothing replaced the jobs.
⭐ Why it still matters
Because it explains the two things Washington took back, and therefore the constitutional resentment you will hear in local politics. It also explains why the Commonwealth's economy has no second leg: when garments went, tourism became effectively the whole economy, and an economy with one leg falls over whenever that leg is kicked.
💹 An Economy With One Leg
Tourism is more than two thirds of GDP. There is almost no agriculture at commercial scale, no manufacturing since 2009, no fishery of consequence landed locally, and no mineral resource. The remainder is federal spending, local government employment and construction.
The last eight years
Read them as a sequence and the picture is unambiguous.
2018
Super Typhoon Yutu crosses Tinian and southern Saipan as a Category 5 — at the time the strongest storm on record to strike any part of the United States. Much of Tinian's housing is destroyed.
2020–22
COVID. An economy dependent on inbound flights from China, Korea and Japan loses all of them. Arrivals fall by well over 90 %. The Commonwealth survives on federal pandemic money.
2023–25
A partial, fragile recovery that never gets back to pre-2018 levels. Anchor businesses close one after another: the Hyatt Regency Saipan ceases operations in 2024; DFS Galleria ends forty years in Garapan in May 2025; ABC Stores closes its Garapan shop.
2026
Super Typhoon Sinlaku on 14 April. The Grandvrio Resort closes after four decades. Airlines cut capacity, fuel costs rise, and federal public meetings are convened in April on “bolstering tourism recovery and air service.” See Typhoon Sinlaku.
⚠️ The casino
Between 2014 and 2021 the Commonwealth staked a great deal on Imperial Pacific International, a Hong Kong-listed operator granted an exclusive Saipan casino licence. The half-finished Imperial Pacific Resort in Garapan reported extraordinary VIP gaming turnover, attracted federal investigations into labour practices and construction deaths, failed to pay its licence fees, closed in 2020 and did not reopen. Litigation and licence proceedings followed.
The building is still there — a large, dark, unfinished hotel in the middle of the tourist district. Whatever else it is, it is the most honest monument in Garapan to what happens when a very small economy bets on a single very large investor.
What remains is a public sector under permanent fiscal strain, a retirement fund that required federal intervention, a population that has been shrinking through outward migration to Guam and the US mainland, and an unusually resilient private sector that has now rebuilt from three catastrophes in eight years.
✈️ Who Comes, and the Politics of That
The Northern Marianas do not have a diversified visitor market. They have had, in sequence, a Japanese market, then a Korean market, then a Chinese market, and the switch between them each time was abrupt and painful.
🇯🇵 Japan
The original market, from the 1970s. Saipan was a three-hour honeymoon and golf destination with direct flights from several Japanese cities. That traffic declined sharply through the 2010s and the direct routes largely disappeared. United restored Tokyo Narita on 2 August 2026; it is a single route, not a market.
🇰🇷 Korea
The mainstay of the last decade. Jeju Air, T'way, Asiana and Korean Air have all served Saipan at various times. Jeju Air resumed Seoul Incheon on 20 June 2026, the first international carrier back after Sinlaku, which tells you where the market is.
⚠️ 🇨🇳 China
The growth market of 2013–19, built on a CNMI-only visa waiver that let Chinese nationals enter the Commonwealth without a US visa. It also drove the casino boom and a wave of birth tourism that became politically contentious. The arrangement has been under sustained federal pressure, and in 2026 the ending of Chinese visa-free travel was reported as a live threat to the islands' recovery — with residents saying so publicly.
The bind
The visa waiver is a federal instrument, granted for federal reasons and revocable for federal reasons that have nothing to do with the Commonwealth's economy. Local government can lobby and cannot decide. It is the same structural powerlessness as the minimum wage and immigration, in a different suit.
🇵🇭 The workforce
A large share of the private-sector workforce is Filipino, and has been for decades — on CW-1 transitional worker permits whose numbers Congress sets and periodically threatens to cut. Bangladeshi, Nepali, Chinese and Korean communities are also substantial. The islands run on people who cannot vote in them.
What this means for you
Menus, signage and hotel service are calibrated for Korean, Japanese and Chinese visitors. English works everywhere. A European visitor is unusual enough to be a small event, and is generally treated very well indeed.
🎖️ The Buildup
The Marianas sit inside the second island chain, and in current American planning that is the line you fall back to when the first one — Japan, Taiwan, the Philippines — is under fire. Guam is the hub. The Northern Marianas are the dispersal.
⭐ Tinian Divert Airfield
The largest visible project: roughly US$300 million to build a divert and contingency airfield on the north side of Tinian's airport, with a runway shared with civil aviation, plus fuel storage, ramp space and support facilities. It was reported at about 80 % complete with final work expected in 2027. Alongside it, the wartime North Field is being cleared and brought back towards usability.
What else
Live-fire and bombing use of Farallon de Medinilla, uninhabited and used as a range since the 1970s. Expanded exercise use of leased Tinian land. Periodic proposals for training on other northern islands — including, controversially, Pagan, whose former residents were evacuated after the 1981 eruption and many of whom want to return.
The local argument for
Jobs, federal money and a functioning airport on Tinian, in an economy that has just lost its third anchor in eight years. Governor Apatang has described the islands as “the first line of defense for the United States of America”, and the Commonwealth has actively sought military investment as economic recovery.
⚠️ The local argument against
Land taken in 1944 and never fully returned is now being taken again for use. Environmental review of range activity on small islands with endemic species is contested. And the late Governor Palacios expressed openly mixed feelings about the buildup — which is roughly where the population is: not opposed, not enthusiastic, and aware that nobody is asking.
What a visitor notices
Very little on Saipan. On Tinian, construction traffic and fenced areas in the north. Occasional exercise periods restrict access to parts of the island — check locally before driving up to North Field, because it does close.
🗳️ How It Is Governed
The structure
A governor and lieutenant governor elected together for four years; a bicameral legislature — a 20-seat House of Representatives and a 9-seat Senate, with the Senate seats divided three each between Saipan, Tinian and Rota regardless of population. Tinian and Rota, with about 2 000 people each, therefore have the same Senate weight as Saipan's 43 000.
The governor
David M. Apatang, sworn in 24 July 2025 on the death of Governor Arnold I. Palacios. Palacios, 69, collapsed in his office on Capitol Hill, was flown to Guam and died the same evening. Senate President Dennis Mendiola became lieutenant governor.
Washington
One non-voting delegate in the House of Representatives — Kimberlyn King-Hinds, elected in 2024 — who sits on committees, speaks, and cannot vote on final passage. No senators. No vote for President, though people born here are US citizens: move to Guam and you still cannot vote for President; move to California and you can.
⚠️ The structural problem
Every decision that has most shaped this economy in thirty years — immigration federalisation, the minimum wage escalator, the China visa waiver, military land use, disaster funding formulas — was made in Washington by people the Commonwealth cannot vote for or against. Whatever you think of the individual decisions, that is the arrangement, and it is the reason local politics is so preoccupied with the Covenant.
Parties
Republican and Democratic labels are used but map poorly onto mainland politics. Local alignment runs on family, village, island and position on land, labour and the military — not on the national culture war.
Corruption
Small-jurisdiction politics with large federal money passing through it has produced a steady flow of federal prosecutions over the decades, of both parties. Locals will tell you about it at length and without much embarrassment.
👥 Who Lives Here
Around 47 000 people, of whom roughly 43 000 are on Saipan and about 2 000 each on Tinian and Rota. The population has been falling for over a decade — through outward migration to Guam, Hawaii and the US mainland, which citizenship makes frictionless, and through the collapse of the industries that brought people in.
⭐ Chamorro
The indigenous people of the whole Mariana archipelago, and the largest single ethnic group in the Commonwealth at roughly a third of the population. Matrilineal clan structure, Catholic, and in the middle of a sustained language and cultural revival.
Refaluwasch (Carolinian)
Descendants of nineteenth-century migrants from the Caroline atolls, concentrated on Saipan — perhaps a tenth of the population. A distinct language, distinct navigation and canoe traditions, and constitutionally recognised alongside Chamorros in matters of land.
Filipino
The largest population group on Saipan by some counts — the backbone of the private-sector workforce for forty years, many now long-settled with US-citizen children, many still on CW-1 transitional permits whose future Congress decides periodically and not always kindly.
Chinese, Korean, Japanese
Chinese communities date substantially from the garment era and the casino years; Korean and Japanese residents from the tourism industry. Bangladeshi, Nepali, Thai and Palauan communities are also present.
⚠️ Land ownership
Article XII of the Commonwealth Constitution restricts permanent ownership of land to persons of Northern Marianas descent. Everyone else leases — for up to 55 years. It has been challenged and upheld, it is fiercely defended locally as the last protection against being bought out, and it is the reason nobody reading this page is going to buy a beach lot here.
The demographic bind
A shrinking citizen population, a workforce that cannot vote, and an emigration route that is wide open because everyone born here holds a US passport. Young people leave for wages three times higher a five-hour flight away. Reversing that is the hardest policy problem the Commonwealth has.
👷 The People Who Cannot Vote Here
This deserves its own section because it is the most consequential everyday fact about these islands and no guidebook mentions it. A very large share of the people who cook your food, clean your room, build the buildings and staff the shops are foreign workers who have lived here for years or decades and have no path to citizenship in the place they live.
CW-1
The Commonwealth-Only Transitional Worker visa, created when immigration was federalised in 2009 as a bridge to let the local economy keep functioning. It was supposed to be temporary and has been extended repeatedly — currently out to the late 2020s. The annual cap is set by Congress and has been cut, restored, and cut again.
⚠️ What that means in practice
A Filipino cook who arrived in 1998, married here, and whose children are US citizens by birth may still hold a permit that is renewed annually at an employer's discretion and could be legislated away. Losing the job means losing the right to be in the country their family lives in.
The numbers
At the peak of the garment era the foreign workforce outnumbered the citizen population. It is smaller now but still a very substantial share of private employment, and the Commonwealth's tourism recovery is not possible without it.
Why it is not simple
Local opinion is genuinely divided. Foreign labour built the economy and holds it up; it also depressed wages for decades and, in the garment years, involved conditions that shamed everybody. Chamorro and Carolinian anxiety about becoming a minority in their own islands — which already happened once, under the Japanese — is not xenophobia in the abstract. It is a memory.
⭐ For a visitor
Be aware that the person serving you may have a more precarious legal position than any migrant worker in Europe and more years in the country than you have been alive. It costs nothing to know that and it changes how you treat people.
🗣️ Three Official Languages
English, Chamorro and Carolinian are all official. English is the language of government, schooling and business, and you will never need anything else. But the other two are alive and using a few words is disproportionately appreciated.
Chamorro / CHamoru
An Austronesian language, related distantly to Filipino and Indonesian languages, with an enormous Spanish loan layer — numbers, days, religion and much household vocabulary came in wholesale. It is classified as endangered: fluent speakers skew old, though immersion schooling and a determined revival movement have pushed back hard over the last two decades.
Refaluwasch / Carolinian
A Micronesian language of the Chuukic group, spoken by a few thousand people on Saipan. More endangered than Chamorro and with fewer institutional supports. Also official, also being taught.
Useful Chamorro
Håfa adai — hello, the universal greeting, pronounced roughly “hafa day”. Si Yu'os ma'åse' — thank you (literally “God have mercy”). Buenas — good day, from Spanish. Adios — goodbye. Guåfi — fire. Tåsi — sea.
Carolinian greeting
Tirow — hello, and a word of respect. You will hear it on Saipan; using it correctly in the right company marks you out as someone who bothered.
Names
Place names run in layers: Chamorro (Puntan Sabaneta, Laderan Banadero, Achugao), Spanish (San Antonio, San Vicente, Chalan Kanoa — chalan being Chamorro for road), Japanese (Garapan retains its pre-war form) and American (Capitol Hill, Beach Road). Signs may use any of them.
⭐ On pronunciation
The å in Chamorro is a low back vowel, closer to the a in “father” than to anything English spells with an a. The glottal stop marked with an apostrophe is a real consonant and dropping it changes words. Nobody will mind if you get it wrong; they will notice if you try.
🎭 Culture and Manners
⭐ Respect for elders
The single most visible social rule. Younger people greet elders by taking their hand and bringing it to the nose to inhale — mangnginge', sometimes called “the sniff” — and it is done in families constantly. You will not be expected to do it; noticing it and not interrupting it matters.
Family and clan
Extended and central. Obligations run wide — to cousins, to the village, to the church. A funeral is a nine-night affair (lisåyu, the rosary) and attendance is expected of a very large number of people. If something is closed, this may well be why.
Church
Catholicism is dominant and practised. Every village has its patron saint, and the fiesta for that saint is the year's social anchor. Protestant congregations, a Japanese Buddhist presence and Filipino and Korean churches are all present.
⚠️ Betel nut
Pugua' — areca nut, wrapped in pepper leaf with slaked lime, often with tobacco. Chewed very widely, especially by older men, and responsible for the red stains you will see on pavements and the red teeth you will see in smiles. It is a genuine carcinogen and a genuine public health problem, and it is also a social ritual — offering betel is hospitality. Decline politely if offered; nobody is offended.
Pace and time
Island time is real and is not rudeness. Government offices keep their hours; nearly everything else is flexible. Rushing people achieves nothing at all.
Dress
Beachwear at the beach, a shirt everywhere else. Church requires covered shoulders. Nobody dresses up much and nobody is impressed by anyone who does.
🎉 Fiesta
If you can time a visit around one, do. A village fiesta is the patronal feast of its church, and it is the most complete expression of Chamorro and Carolinian social life you will encounter.
The pattern: a novena in the days before, a Mass and a procession carrying the saint through the village on the day, and then open houses all afternoon and evening. Families cook for days. Tables are set out under canopies and loaded with red rice, barbecue, kelaguen, kadon pika, empanada, and cake. And then — the part that surprises visitors — you are fed whether or not anybody knows you. Turning up as a stranger is not gatecrashing; being fed by strangers is the point.
How to do it right
Go with someone local if you can. Bring something — a tray of food, drinks, money in an envelope for the host family is normal at some events. Eat. Accept seconds. Do not photograph people without asking, especially inside houses. Say Si Yu'os ma'åse' when you leave.
The calendar
Fiestas run through the year, one village at a time. San Isidro in Chalan Kanoa in May, San Antonio in June, Santa Soledad on Tinian, San Francisco de Borja on Rota in October. Ask at your hotel or the visitors authority — they will know what is on and will usually tell you to go.
Other events
Liberation Day, 4 July — a fortnight-long carnival in Garapan marking the end of the 1944 internment, and the biggest annual event. Flame Tree Arts Festival in spring. Micronesian games and canoe events when they come round.
⚠️ After Sinlaku
Events in 2026 have been disrupted, reduced or cancelled outright as villages rebuilt. Check before making plans around any specific fiesta.
🌲 Taotaomo'na
Chamorro belief holds that the spirits of the ancestors — taotaomo'na, “the people of before” — remain in the land, particularly in the old forest, in banyan trees (nunu), in caves and at latte sites. They are not ghosts in the European sense. They are the previous occupants, they have standing, and they can be offended.
The practical rule, which almost everyone here follows and which you should follow too, is that before urinating in the bush or disturbing anything in the jungle you ask permission: Guela yan guelo, kao siña yo' fumåtto gi tano'-miyu? — grandmother and grandfather, may I pass through your land? People say it. Serious, educated, entirely modern people say it.
Why you should too
Not because you must believe it. Because it costs you one sentence and it signals that you understand you are a guest on land that belongs to people who were here first — which is, under everything else, precisely what this page has been about.
Where it applies
Old forest, banyan groves, caves, latte sites, anywhere obviously untouched. Not hotels, roads and beaches. If a local guide stops and says something quietly before you go in somewhere, that is what they are doing.
⭐ The marks
Unexplained bruises or illness after disturbing a site are attributed to taotaomo'na and the stories are common. Treat them the way you would treat any belief held by people whose hospitality you are accepting: without mockery.
Catholicism and this
Coexist without much visible friction. The same family will attend Mass on Sunday and ask the ancestors' permission on Monday, and see no contradiction in it. Four hundred years of Catholicism laid on top of something older did not erase it.
🏝️ Saipan
115 km², around 43 000 people, and everything happens here. A sheltered lagoon down the whole west side, a limestone spine in the middle, cliffs in the north and east, and a road that goes round most of it in ninety minutes if you do not stop. You will stop.
Mount Tapochau
474 m, the high point, reached by a rough road that wants a four-wheel drive or a decent walk. From the top you see the whole island at once — lagoon, reef, Tinian across the channel, and on a clear day the northern islands as smudges. It was the key ground in 1944 and it is obvious why the moment you stand on it.
⭐ Managaha
A small coral islet in the lagoon, reachable by boat from Garapan in fifteen minutes, ringed by white sand and clear shallow water and the best easy snorkelling in the Commonwealth. It is also a burial place of the Carolinian chief Aghurubw, who led the nineteenth-century migration, and there is a monument. Day-trip operations run to it; check what has reopened after Sinlaku.
Bird Island
An offshore limestone stack on the north-east coast with a signposted overlook. A sanctuary, dramatic in the morning light, and one of the standard stops on the northern circuit.
Grotto
A collapsed limestone cavern on the north-east coast connected to the open sea by three underwater openings. It is the Commonwealth's most famous dive site — see Diving — and you can look down into it from the top of a long flight of concrete steps without getting wet, which is worth doing on its own.
Marpi
The northern end: Banzai Cliff, Suicide Cliff, the Last Command Post, and a landscape of memorials in several languages. Treated properly in War sites.
Capitol Hill
The seat of government, in the hills above Garapan — built as the administrative centre of the Trust Territory and, before that, the site of the CIA's closed-years training facility. Not a sight, but the answer to “where is the capital”, which is a question with a slightly odd answer here.
🏪 Garapan
The tourist town, on the lagoon halfway up the west coast, and the only place in the Commonwealth with anything like a street life. It is also a good short lesson in the last ten years, because a fair number of its landmarks are now closed.
What is there
Beach Road and the streets behind it: hotels, restaurants, dive shops, bars, massage places, Korean barbecue, Japanese izakaya, Filipino canteens, convenience stores. The American Memorial Park at the north end. The street market on Thursday evenings, which is the single best cheap meal in the islands and the easiest way to meet anybody.
⭐ American Memorial Park
A US National Park Service site commemorating the Americans and the Chamorro and Carolinian civilians who died in the Marianas campaign. The visitor centre has the best museum exhibition on the 1944 fighting anywhere in the islands and it is free. Start here before you go to Marpi; it will make the sites legible.
NMI Museum of History and Culture
In the restored Japanese hospital building. Chamorro and Carolinian material, latte, the Spanish and German periods, the Japanese era, and the archaeology. Small, good, underfunded and worth an hour.
Sugar King Park
Matsue Haruji's statue, a surviving sugar locomotive, and a Japanese shrine, in a small park in the middle of town. The most concentrated physical remnant of the plantation years.
Old Japanese Jail
Pre-war concrete cells, roofless and overgrown, a short walk from Beach Road. Persistent local legend says Amelia Earhart was held here after 1937. There is no evidence for it — no contemporary record, no credible physical trace, and the serious research consistently comes up empty. It is a good ruin and a bad story and this guide is not going to print the story as fact.
⚠️ What closed
The Hyatt Regency Saipan ceased operations in 2024. DFS Galleria ended forty years in Garapan in May 2025. ABC Stores closed its Garapan shop. The unfinished Imperial Pacific Resort looms over the middle of it all. Then came Sinlaku. Expect gaps.
🛩️ Tinian
Five kilometres across the channel, 101 km², around 2 000 people, one small town and a great deal of nothing. Reached by a short flight from Saipan, or by ferry when one is running — check, because the service has been intermittent.
⭐ North Field
The four wartime runways, the Manhattan street grid, the Japanese bunkers, and the atomic bomb loading pits from which the Hiroshima and Nagasaki missions were flown. See Tinian and North Field. Access can be restricted during military exercises — ask before you drive up.
⭐ House of Taga
The largest latte stones anywhere, one still standing. A thousand-year-old Chamorro monument twenty minutes from the atomic bomb pits, and the pairing is the most extraordinary thing on offer in these islands.
Taga Beach and Chulu (Unai Dankulo)
Small, beautiful and usually empty. Taga Beach is a limestone cove with a cliff people jump off; Chulu, the “long beach”, is a wide stretch on the east coast where the swell comes in.
Blow Hole
On the eastern shore, where swell forces through a limestone channel and fires water upward. Genuinely impressive when the sea is up and completely inert when it is not.
San Jose
The town: a few streets, a church, a couple of restaurants, a store. This is the whole urban extent of the island, and after Yutu in 2018 and Sinlaku in 2026 a good deal of it has been rebuilt twice.
⚠️ Practicalities
Take a vehicle or book a guide. There is essentially no public transport and the distances are real. Bring water and fuel. Accommodation is minimal — check what is open before you commit to an overnight.
🌺 Rota
The quiet one. 85 km², about 2 000 people, and the only one of the three that was not fought over — the garrison was bypassed in 1944 and surrendered in 1945. That single fact is why Rota has the forest, the birds and the archaeology that Saipan and Tinian lost.
⭐ As Nieves latte quarry
The most eloquent archaeological site in the Marianas: a hillside where latte pillars and capstones lie half-cut from the living rock, abandoned mid-work, some of them larger than anything ever erected. You can see exactly how it was done. There is nothing else like it anywhere.
The birds
The Rota white-eye (Zosterops rotensis) exists on this island and nowhere else on earth, in a patch of forest on the Sabana. The Mariana crow (åga), functionally extinct on Guam, survives here. The Rota Bird Sanctuary overlooks a seabird colony on the cliffs. If you care about birds at all, this is the reason to come to the Commonwealth.
Songsong and Sinapalo
The two villages. Songsong sits on a narrow neck under Wedding Cake Mountain (Taipingot), which is as photogenic as the name suggests. Sinapalo is inland near the airport.
Swimming Hole and Tweksberry
Natural pools in the reef flat on the north coast, sheltered from the swell, and some of the best easy snorkelling in the islands. The Guata (Swimming Hole) is the standard stop.
Tonga Cave and the Japanese cannon
A large limestone cave used as a shelter in the war, and preserved Japanese coastal guns above Songsong — war relics without a battlefield attached, which makes them read very differently from Saipan's.
⭐ Why go
Because it is what Saipan was before 1935. Almost no tourism infrastructure, very few visitors, a forest that is genuinely intact, and people who will talk to you all afternoon. Flights from Saipan are short and have been irregular; confirm before booking anything non-refundable.
🌋 The Northern Islands
Eleven islands north of Saipan, running 500 km up the volcanic arc, and essentially nobody lives on any of them. They are the least-visited part of the United States.
Pagan
The largest and the most argued about. Two volcanoes joined by an isthmus, black sand beaches, hot springs and a lake. It had a permanent community until the 1981 eruption forced an evacuation. Former residents and their descendants have pressed for return ever since; proposals to use the island for military training have made that a live political fight.
Anatahan
Erupted violently in May 2003 with no recorded historical precedent, sending ash to 10 km and closing air routes. It had been evacuated in the 1990s. It is also the site of one of the strangest stories of the war — a small group of Japanese stranded there held out until 1951, six years after the surrender.
Agrihan
The highest point in the Commonwealth at 965 m — a single steep cone rising straight out of deep water. Occasionally inhabited by a handful of people, usually not.
Maug
Three islets that are the rim of a drowned caldera, enclosing a flooded crater with hydrothermal vents on its floor. Inside the Marianas Trench Marine National Monument and one of the more remarkable marine sites on earth. Effectively inaccessible.
Farallon de Pajaros (Uracas)
The northernmost, a permanently steaming active cone that nineteenth-century whalers used as a navigation light. Uninhabited and uninhabitable.
⚠️ Getting there
You very likely cannot. There is no scheduled service. Access is by occasional government or charter vessel, requires permission, and several islands lie inside the Monument with their own restrictions. If a tour operator promises you Pagan casually, be sceptical.
🕊️ The War Sites, and How to Visit Them
This is the densest concentration of Pacific War ground you can reach on a normal holiday, and it is also a mass grave. How you go matters.
Banzai Cliff (Puntan Sabaneta)
The low cliff at the northern tip from which civilians jumped in July 1944. Japanese memorials line the approach, placed by families and by prefectural associations over decades. People still come to pray here. It is a cemetery in everything but name.
Suicide Cliff (Laderan Banadero)
The high escarpment above it, with the same history and a wider view. A road runs to a viewpoint with memorials in Japanese, Korean and English. The Korean memorial matters: a large number of those who died here were Korean forced labourers, and that part of the story is very often left out.
Last Command Post
A concrete bunker built into the cliff at Marpi, with Japanese guns and tank hulks around it. Saitō's final headquarters. Free and open.
The invasion beaches
South of Garapan, with markers. There are amphibious tanks still sitting on the reef flat offshore, visible and snorkellable, which is the most immediate way to grasp what happened here.
American Memorial Park
The National Park Service site in Garapan — the visitor centre, the Court of Honor with the names of the American dead, and the wetland behind it. The place to understand the campaign before you go and look at the places it happened.
⚠️ How to behave
Do not climb on memorials. Do not remove anything — ordnance, bones, relics; live ammunition is still found and the bones are somebody's family. Ask before photographing people praying. Do not treat Banzai Cliff as a viewpoint with a nice backdrop. If that seems obvious, visit and watch how many people do exactly that.
🤿 Diving and the Water
The best single reason to come, and the Commonwealth's most genuinely world-class asset. Water temperature around 28 °C year-round, visibility routinely 30 metres and more outside the lagoon, and a set of sites that includes one of the most famous cavern dives in the world.
⭐ The Grotto
A collapsed limestone chamber on the north-east coast linked to the open Pacific by three underwater holes. You descend a long concrete stair into the cavern, enter a pool of extraordinary blue, and swim out through the holes into open water — or stay inside and watch the light shafts move. It is not a beginner dive. Surge through the holes can be severe, entry and exit over wet rock is genuinely dangerous in swell, and people have died here. Go with a local operator, go on a calm day, and take the briefing seriously.
Wrecks
Japanese ships and aircraft in and around the lagoon and at Tanapag — Shoan Maru, the Emily flying boat, B-29 wreckage, landing craft, tanks on the reef flat. Much of it is shallow and some of it is snorkellable. It is a war grave as well as a dive site and should be entered as one: nothing taken, nothing moved.
Eagle Ray City / Ice Cream
Lagoon sites, shallow and easy, with reliable eagle rays and turtles. The right place for a first dive or a refresher.
Obyan and Lau Lau
Lau Lau Beach is one of the largest shore-entry dive sites in the world — a gently shelving bay on the east coast with coral gardens, turtles and a long swim to anything deep. Obyan, in the south, has good reef and Japanese defensive positions on the beach behind it.
Rota
The Shoun Maru wreck, the Senhanom Cave, and the best visibility in the archipelago. Fewer operators, fewer divers, better water.
⚠️ Safety and Sinlaku
There is a recompression chamber on Guam, not here; a serious hit means an evacuation flight. Dive conservatively. And note that Sinlaku damaged shore access, stairs, moorings and some coral — check with operators what has reopened and what the sites actually look like now.
🍽️ Chamorro Food
Chamorro cooking is a genuine cuisine and almost nobody outside the Marianas has heard of it. It is built from Austronesian technique, four hundred years of Spanish and Filipino influence, thirty years of Japanese, and eighty of American — and the result tastes like nowhere else.
The five things to eat
⭐ Kelaguen
The national dish and the one to try first. Protein “cooked” in lemon juice — lemmai, the local lemon, or calamansi — then tossed with grated fresh coconut, chopped onion and donne' sali, the tiny incendiary local chilli. Chicken kelaguen is grilled first and chopped; shrimp and beef kelaguen are common; the classic version uses raw fish or raw tollai hilitai. Eaten with titiyas.
Red rice
Rice coloured and faintly flavoured with achote (annatto) seeds steeped in water, often finished with a little coconut milk and sometimes bacon or onion. It is on every fiesta table and every plate lunch, it is not spicy, and it is the carbohydrate that defines a Chamorro meal.
Kadon pika
Chicken stewed with coconut milk, vinegar, onion, garlic and a serious quantity of donne'. Pika means spicy and it means it. The coconut milk takes the edge off without reducing the heat, which is the trick of the dish.
⭐ Fina'denne'
Not a dish — the sauce, and the thing you will miss when you leave. Soy sauce, lemon juice or vinegar, sliced onion, and chopped hot pepper. That is all. It sits on every table, it goes on everything including the rice, and every family has a version they will tell you is the correct one.
Barbecue
Short ribs and chicken marinated in soy, vinegar, garlic and black pepper, grilled over wood or charcoal, served with red rice and fina'denne'. The single most common meal in the islands and the backbone of every fiesta, fundraiser and roadside stand.
Apigigi and titiyas
Apigigi: young coconut and cassava, wrapped in banana leaf and grilled until the leaf chars and the inside sets — sweet, smoky, extraordinary. Titiyas: flatbread made with corn flour or coconut, the standard accompaniment to kelaguen.
Where to eat it
Not, mostly, in hotels. Chamorro food lives at roadside barbecue stands, at the Thursday night street market in Garapan, at village fundraisers, and at fiestas. The market is the best single meal available in the Commonwealth: a street closed off, a dozen stalls, plate lunches for a few dollars, and the entire island there.
Alongside it you will find excellent Filipino food (this is one of the great under-rated Filipino food destinations, simply because of who lives here), Korean barbecue and stews, Japanese izakaya and ramen, and Chinese cooking from several regions. After Sinlaku, opening hours have been irregular — ask rather than assume.
👨🍳 Three Recipes You Can Actually Cook
Adapted for a European kitchen with honest substitutions. Where the substitution changes the dish, this page says so.
Chicken Kelaguen
Serves 4 · Prep 20 min · Grill 20 min · The national dish
Ingredients: 4 chicken thighs, bone in, skin on; juice of 4–6 lemons (about 150 ml); 1 fresh coconut, flesh grated — or 150 g unsweetened desiccated coconut, rehydrated in 100 ml hot water and cooled; 1 small onion or 4 spring onions, very finely chopped; 2–4 bird's-eye chillies, finely chopped, or more; 1 tsp salt.
Method: Grill the chicken over charcoal, or under a very hot grill, until the skin is properly charred and the meat is cooked through — the char is a flavour, not an accident. Let it cool enough to handle, then strip the meat off and chop it fine with a knife; do not shred it and do not use a food processor. Put it in a bowl with the lemon juice and the salt and leave it for ten minutes. Add the coconut, onion and chilli, mix thoroughly with your hands, taste, and correct the lemon and the salt — it should be sharp, coconut-rich and hot. Serve at room temperature with titiyas or warm flatbread and plain rice.
💡 Fresh coconut is the whole point and desiccated is a real compromise: rehydrate it properly and add a spoon of coconut cream to get part of the way back. Use more lemon than feels sensible. Chamorro cooks use donne' sali, which is far hotter than a bird's-eye — scale up if you can take it.
Kadon Pika
Serves 4 · Prep 10 min · Cook 45 min · Hot, and meant to be
Ingredients: 1 kg chicken thighs and drumsticks; 1 large onion, sliced; 6 cloves garlic, sliced; 400 ml coconut milk; 4 tbsp white or cider vinegar; 2 tbsp soy sauce; 6–12 bird's-eye chillies, whole or split depending on nerve; 2 bay leaves; 1 tsp black pepper; 2 tbsp oil; salt.
Method: Brown the chicken in the oil in a heavy pan and set aside. Soften the onion, add the garlic for a minute, then return the chicken with the vinegar, soy, bay and pepper and let it bubble for two minutes without stirring so the vinegar cooks off its raw edge. Add the coconut milk and the chillies, bring to a bare simmer and cook uncovered for 30–35 minutes, until the sauce has reduced and separated slightly and the chicken is falling off the bone. Taste for salt. Serve with red rice.
💡 Split chillies release far more heat than whole ones — start whole, split some at the end if you want more. If it looks like it is going to split unpleasantly, drop the heat; coconut milk does not like a hard boil.
Red Rice and Fina'denne'
Serves 4–6 · Prep 15 min · Cook 20 min · Everything else goes on top of these
Ingredients: Red rice: 400 g long-grain or jasmine rice; 2 tbsp achote (annatto) seeds; 600 ml water; 1 small onion, finely chopped; 1 tbsp oil or 2 rashers bacon, chopped; 1 tsp salt. Fina'denne': 4 tbsp soy sauce; 2 tbsp lemon juice or white vinegar; 1 small onion or 4 spring onions, thinly sliced; 2–4 bird's-eye chillies, chopped.
Method: Red rice: steep the achote seeds in the 600 ml of warm water for 15 minutes, squeezing them with your fingers until the water is deep orange-red, then strain the seeds out and discard them — they are a colour, not an ingredient. Soften the onion (with the bacon, if using) in the oil in the pan you will cook the rice in. Add the washed rice, stir to coat, pour in the achote water, add the salt, bring to the boil, cover and cook on the lowest heat for 15 minutes, then rest off the heat for 10 more. Fork through. Fina'denne': stir everything together in a small bowl and leave it for at least twenty minutes.
💡 Achote seeds are sold as annatto in Latin American and Caribbean shops and keep for years. Do not substitute paprika — wrong colour, wrong flavour, wrong dish. The fina'denne' improves for a day in the fridge and is very good on almost anything you already cook.
🍹 Drinks
⭐ Tuba
Fermented coconut sap, tapped from the cut flower stalk and collected in a container hung on the tree. Drunk fresh it is sweet and barely alcoholic; left a day it becomes sour and properly alcoholic; left longer it becomes vinegar. It is a village drink rather than a bar drink — if somebody offers you some from a plastic bottle, that is the real thing.
Aguayente
Tuba distilled. Clear, strong and made informally. Approach with the respect you would give any home-distilled spirit in any country.
Ahu
Grated young coconut in coconut water, sometimes sweetened. Non-alcoholic, cold, and the correct thing to drink in the middle of a hot afternoon.
Beer
American, Japanese and Korean brands, cold and everywhere. Budweiser and Bud Light are ubiquitous for historical reasons nobody defends. Miller, Asahi, Kirin, Hite and Cass all turn up.
Coffee and the rest
American-style coffee, Korean cafés, Japanese vending-machine culture in places. Soft drinks are American and cheap by European standards.
⚠️ Water
Tap water quality varies by area and has been affected by storm damage and infrastructure age. Drink bottled or filtered, which is what most residents do. It is inexpensive and universally available.
A note on alcohol law: this is the United States, so the drinking age is 21 and it is enforced, including on people who are obviously older and have a European driving licence. Carry ID.
💰 Costs — Honest Numbers
The currency is the US dollar and the price level is American, not Pacific-cheap — everything except fish and local produce is shipped in. Figures below are indicative for 2026, converted to Czech crowns at a rough working rate. Post-Sinlaku supply and pricing have been volatile; treat these as an order of magnitude.
🥗 Eating
Plate lunch or street-market meal: 200–350 Kč. Filipino or Korean restaurant dinner: 350–600 Kč. Hotel restaurant: 700–1 400 Kč. Beer in a bar: 100–150 Kč. Supermarket prices are high — imported groceries cost noticeably more than in Prague.
🛏️ Sleeping
Simple guesthouse or small hotel: 1 500–2 500 Kč a night. A functioning beach resort in Garapan: 2 500–5 000 Kč. Tinian and Rota accommodation is limited and priced accordingly. Confirm directly what is open and what works before paying.
🚗 Car hire
800–1 500 Kč a day. You will need one — there is effectively no public transport on Saipan and none at all on Tinian and Rota. An ordinary EU or Czech licence is accepted for short visits; an international permit removes any argument.
🤿 Diving
Two-tank boat dive: 2 500–3 500 Kč. Shore dive with guide: 1 500–2 500 Kč. Equipment rental on top. The Grotto is usually priced as a guided dive and should be.
🏛️ Sites
American Memorial Park is free. The NMI Museum is a few dollars. Marpi sites, North Field and the latte sites are free and unstaffed. Managaha has a landing fee plus the boat. This is a cheap destination for sightseeing and an expensive one for everything else.
💳 Money
US dollars, US cards, US ATMs — everything works normally, which after some other pages in this atlas is worth saying plainly. Tipping is American: 15–20 % in restaurants. Keep some cash for market stalls and small operators.
A realistic daily budget for two travelling independently with a hire car, eating a mix of street and restaurant food and diving every other day: 6 000–9 000 Kč per day for the pair, accommodation included. The flights, not the stay, are what make this an expensive trip from Europe.
📋 Practical
⚠️ Before anything else
Check current conditions. Super Typhoon Sinlaku hit on 14 April 2026 and recovery is advanced but incomplete: airport hours, flight schedules, hotel amenities, dive site access and restaurant opening are all still moving. The Marianas Visitors Authority publishes recovery updates and they are the thing to read, not a guidebook.
🛂 Entry
This is the United States. Czech citizens travel under the Visa Waiver Program with an ESTA, which since 1 January 2026 costs US$40.27 (raised from $21 in September 2025). Apply on the official CBP site — esta.cbp.dhs.gov — and not through any of the many lookalike sites that charge several times as much. Passport valid for the stay, return or onward ticket, 90 days maximum.
✈️ Getting there
There are no direct flights from anywhere in Europe and there never will be. Realistic routings are via Seoul Incheon (Jeju Air, resumed 20 June 2026), Tokyo Narita (United, resumed 2 August 2026), Manila (Philippine Airlines, expected back October 2026) or via Guam, which has better connections and a short hop to Saipan. Saipan International has been operating daytime flights only.
🗓️ When to go
December to June is the dry season and the right answer. July to November is wet and is typhoon season — Yutu hit in October, Sinlaku in April, so the season is not an absolute guide, but the odds are what they are. Temperatures are 27–30 °C all year; humidity is the variable.
🚗 Getting around
Hire a car. Drive on the right, American road signs, cheap fuel by European standards, and short distances. Saipan's roads took storm damage — potholes and unlit sections are real. Tinian and Rota need a vehicle booked in advance because there are very few.
📶 Connectivity
US mobile networks (IT&E, Docomo Pacific). Your European roaming will treat this as the USA and charge accordingly — check your tariff, because some Czech operators exclude US territories from their US bundles. A local SIM or eSIM is cheap. Hotel wifi is variable and was damaged.
🏥 Health and safety
Commonwealth Health Center on Saipan is the main hospital; serious cases are flown to Guam or Hawaii, and that flight is extremely expensive. Travel insurance with medical evacuation cover is not optional here. No malaria, no dengue endemic transmission of note, no dangerous land animals. Crime against visitors is low. Sun, surf and dive accidents are the actual risks.
Two specific warnings
Water. The reef passes and the eastern coasts have strong currents and there are drownings every year, including of strong swimmers. Swim inside the lagoon unless you are with someone who knows the site. Do not enter the Grotto from the rocks in swell.
Unexploded ordnance. Eighty years on, live munitions still turn up in the bush and on beaches after storms — and Sinlaku moved a great deal of ground. Do not pick anything up. Report it and walk away.
🇨🇿 For Czech Readers
This is one of the harder destinations to reach from Prague in this atlas — roughly 24 to 30 hours door to door with two or three connections, and no way to shorten it.
✈️ Route 1 — via Seoul
Prague → Seoul Incheon → Saipan. Incheon is the most reliable gateway: it is the market that keeps Saipan flying, and Jeju Air resumed the route on 20 June 2026. Reaching Incheon from Prague usually means one European or Gulf connection. Budget roughly 30 000–45 000 Kč return.
✈️ Route 2 — via Tokyo or Guam
Prague → Tokyo Narita → Saipan with United, restored 2 August 2026; or via Guam, which has more connections from Tokyo and Manila and a short hop onward. Guam is often easier to route and lets you see both territories. Similar price.
🛂 ESTA, not a visa
Czech citizens use the Visa Waiver Program. Apply for an ESTA at esta.cbp.dhs.gov — the official site, cost US$40.27 since 1 January 2026. Do it at least 72 hours ahead. Beware commercial lookalike sites; they are legal, they are useless, and they charge three to five times the fee.
⚠️ ESTA disqualifiers
The VWP excludes anyone who has travelled to certain countries since March 2011 — the list includes Iran, Iraq, Syria, Sudan, Libya, Somalia, Yemen, North Korea and Cuba — and anyone holding those nationalities. If that applies, you need a real B-2 visa from the US embassy in Prague, which takes months. Check before you book.
📋 MZV ČR
The Czech foreign ministry's information for the United States covers the territories. There is no Czech consular presence in the Marianas; the nearest is the embassy in Washington and the honorary network, and practical help would come through them at considerable distance. Read mzv.gov.cz before you go.
📝 DROZD
Register at drozd.mzv.gov.cz. It is free, it takes five minutes, and this is exactly the destination it was built for: a remote archipelago with one hospital, a live typhoon risk, and the nearest Czech diplomat on the other side of the planet. Sinlaku is the argument.
A Czech reader's checklist
ESTA from the official site, well in advance. Travel insurance that explicitly covers medical evacuation — the flight from Saipan to Guam or Honolulu is the cost that ruins people, and your Czech policy's standard limits may not touch it. Check whether your mobile tariff's “USA” bundle includes US territories, because several do not. Book the hire car before you arrive. Register in DROZD. And check the Marianas Visitors Authority recovery page the week you fly, because what is open has been changing month to month since April.
One thing in your favour: everything financial works. Dollars, cards, ATMs, American consumer protection, American aviation rules. After some of the other pages in this atlas, that is a holiday in itself.
✍️ Author's Note
Two things about this page are worth saying straight out.
The first is the pictures
There are none, except one. The bucket for this territory holds a single image — a limestone headland at sunset — and the page it replaces had a heading reading “📸 Photo Gallery” under which the images had src="". Empty attributes. A gallery that was furniture.
So a territory whose entire draw is war sites, diving and beaches is illustrated here by one generic cliff, and I have said in its caption exactly what is right about it (raised limestone with a wave-cut notch is this coast) and what is wrong (nothing identifies these islands, and the cliffed coasts face east into the trade winds, where the sun rises and the sea is not glass). I would rather run one honestly captioned image than five confident ones I cannot vouch for.
The second is the typhoon
I have put Sinlaku near the top of the page rather than filing it under history, because on 15 September 2026 it is not history. Five months after a Category 5 storm, a place with 47 000 people and one hospital is still working through it. Any guide that opens with palm trees and closes with a packing list, and puts the typhoon in a box near the bottom, is lying to you by arrangement.
The reason I have been careful with the dates and the reopening details is that they are the difference between a good trip and a wasted one, and they are also the thing that goes stale fastest. Everything in that section came from reporting between April and September 2026. Check it again before you fly.
And a third thing, less tidy
This page has four colonial administrations in it, a battle that killed tens of thousands of people in twenty-five days, an airfield from which two atomic bombings were flown, a garment industry that indentured people under a Made in USA label, and a workforce that holds the place up and cannot vote in it. Underneath all of that is a people who have been here for three and a half thousand years, whose language nearly died and did not, and who will feed you at a fiesta without asking who you are.
I have tried to keep those in proportion to each other. If the balance is wrong somewhere — or a date, a price, a name or a claim is wrong — I would rather know. Corrections are welcome and will be made.
