Ogasawara Islands

There is no airport on Chichijima. The only way to reach Japan’s Ogasawara Islands is a 24-hour ferry from Tokyo, which departs roughly once every six days. That single timetabling fact is responsible for everything that makes Ogasawara exceptional: the near-total absence of day-trippers, the functioning village economy, the silence, and the ecosystems that have evolved undisturbed since these volcanic islands first rose from the Pacific without ever touching a continent.

Because Ogasawara has never had a land connection, every species that arrived there came by wing, wind, or ocean current and then adapted in isolation. The result is an endemism rate that approaches the extraordinary: around 94 percent of land snail species are found nowhere else on Earth, as are roughly 70 percent of woody plants. Evolutionary biologists treat the islands as a working laboratory for studying speciation, comparable in that respect to the Galapagos, though with far fewer tourists.

Getting There

The Ogasawara Maru departs from Takeshiba Passenger Ship Terminal in central Tokyo, a one-minute walk from Yurikamome Takeshiba Station. The crossing to Futami Port on Chichijima takes approximately 24 to 26 hours depending on sea conditions. The ship runs roughly every six days on a regular schedule, with more frequent departures during peak seasons such as late July and August.

One-way fares range from around 30,000 yen for a basic shared berth to 90,000 yen for a private cabin, with prices varying by season and berth class. Cabins sell out weeks in advance during summer school holidays and Golden Week; reserve as soon as you have fixed dates. The Ogasawara Kaiun company website handles bookings in Japanese, but the ferry is manageable with translation tools and most guesthouses on Chichijima will assist first-time visitors with the process.

The timing of the ferry schedule determines how long you stay. Because it departs both ways on a fixed six-day cycle, most visitors stay for approximately six days before catching the return sailing. You can stay for twelve days or longer by staying for two cycles, which is the better option for divers or hikers who want unhurried time.

The Islands and What to Do

Chichijima is the main island, home to the village of Oki-mura, most of the guesthouses and restaurants, and the principal beach at Minamizaki. Hahajima, a three-hour boat ride from Chichijima, is smaller, quieter, and has some of the most concentrated endemic forest remaining. It is worth making the trip to Hahajima even if only for two days; the visitor numbers are lower and the birdlife is exceptional.

Whale-watching and dolphin encounters are among the most reliable wildlife activities in Japan here. Sperm whales, humpbacks, and minke whales pass through the surrounding waters on seasonal migrations, and spinner dolphins are often encountered on snorkelling tours. The dive sites are genuinely world-class: clear warm water, hard coral in good condition, and pelagic species including manta rays and green sea turtles.

Hiking on Chichijima and Hahajima requires permits and in many areas a licensed guide. The regulations exist because alien plant and seed species introduced on boots and clothing represent the primary modern threat to the endemic ecosystem. Before entering forest areas, you will be required to clean the soles of your shoes at disinfection stations. This is not optional and should not be resented; it is directly responsible for the fact that the forest you are about to walk through still exists.

The island of Minamijima, a short boat ride from Chichijima, has a sea cave and reef system with remarkable snorkelling but is strictly access-controlled. Entry requires a licensed local guide and visitor numbers are capped daily to prevent erosion damage.

World War II History

Chichijima and the surrounding waters were the site of significant fighting during 1944 and 1945. A small American cemetery and various bunkers and coastal fortifications remain on the island. George H.W. Bush was shot down near Chichijima in September 1944 and rescued from the sea by a US submarine; his fellow airmen who reached shore were killed. The local museum covers both the prewar American and European settler history of the islands and the wartime period, and is worth visiting on the first or second day of your stay to provide context.

Practical Matters

Accommodation on Chichijima is concentrated in guesthouses (minshuku) run by local families, most of which include two meals per day in the rate. The standard of food is high; the fish is exceptionally fresh. Book well in advance for summer visits; options fill up the day ferry reservations open.

The islands are subtropical. From October to April, temperatures are pleasant and humidity is manageable. May through September is humid, warm, and frequently rainy, but the sea is calm enough for diving throughout. December and January can have choppy ferry crossings.

There are no ATMs on the islands that reliably accept foreign cards; bring sufficient cash from Tokyo. Mobile data coverage exists across most of Chichijima but is limited on Hahajima’s more remote trails. The pace of island life is slow and deliberate, tied to ferry schedules. Lean into that rather than resist it.
