Climate

The Ogasawara Islands lie within the subtropical zone and enjoy warm weather throughout the year, with little seasonal variation in temperature. On fine days, it’s comfortable enough to wear short sleeves or a light long-sleeved shirt—even in winter. Sea conditions, particularly on the outside deck of the Ogasawara Maru ferry or on tour boats, can be windy, so bringing a windbreaker is recommended. Sandals are a convenient choice for strolling around the town of Chichijima. During boating excursions, be sure to take appropriate precautions against sun exposure. While the waters remain inviting year-round, wearing a wetsuit is essential for snorkeling and swimming with dolphins in winter. Wetsuits and snorkeling gear are available for rent on site for an additional fee.

The Best Time to Dive in Ogasawara

You can enjoy diving in the Ogasawara Islands year-round. Water clarity and the marine life you may encounter vary with the seasons. From early summer to autumn, visibility improves and sea conditions become more stable.

Winter (January to March)
Humpback whales that spent the summer in northern waters migrate to the area around the Ogasawara Islands to breed and raise their young. This is a great season for whale watching between dives. It’s also a time when sightings of the elusive Sandtiger shark are more likely.
Water temperature: 19–20°C (66–68°F)

Spring (April to June)
April continues to offer opportunities to spot humpback whales and possibly Sandtiger shark. Green turtles become more frequent, and schools of Wrought iron butterflyfish can be seen. Around this time, the winds begin to calm.
Water temperature: 22–26°C (71–79°F)

Summer (July to September)
This season boasts excellent visibility and stable conditions—though typhoons may occur. Dogtooth tunas begin to gather, and dolphins are often seen, making dolphin swims in just a swimsuit possible.
Water temperature: 27–28°C (80–82°F)

Autumn (October to December)
Clear water persists through November, with possible sightings of bull ray schools. When sea conditions are favorable. In December, the water begins to cool and humpback whales start arriving gradually.
Water temperature: 24–26°C (75–79°F)

About the Ogasawara Maru Ferry

Ogasawara does not have an airport, so the only access is by ferry. The ferry liner Ogasawara Maru sets sail once a week from Takeshiba Ferry Terminal in Tokyo.
Travelers should plan for a six-day round trip to the Ogasawara Islands. The ferry departs from Takeshiba at 11:00 A.M. and takes approximately 24 hours to reach its destination, arriving at Futami Port on Chichijima Island at 11:00 A.M. the following day.
The ferry is equipped with facilities such as a restaurant, café, and shops, ensuring comfort during the voyage. There are multiple cabin classes available across five decks, with a range of pricing options. The tour includes an Economy Berth (upper and lower bunk beds with privacy curtains, facing each other).
If you wish to upgrade to a Premium Berth, Standard Twin Room, Deluxe Room, or Suite, or switch to a lower-priced Japanese-style Economy cabin, please let us know your preference.

Accommodations

Chichijima Island does not have large hotel facilities, so lodging will be arranged at a small guest house. Western-style rooms with beds may not be guaranteed. Additionally, many accommodations offer only shared bathrooms (toilets and shower areas). Since most guest houses have a limited number of rooms, securing a single-room reservation may not be possible. In some cases, group members may need to stay at separate locations. Some accommodations do not provide breakfast. In such cases, breakfast will be excluded from the tour package, and participants may purchase it from a local shop.

Dietary Restriction

Hotels in remote area such as Eastern Hokkaido may only accept requests for special meals.

Note

** On the day of your boat tour in Chichijima, please purchase your lunch at a local shop beforehand and bring it with you. There are plenty of dining options available on the island for dinner.
** Only a limited number of stores and restaurants in Ogasawara accept credit cards, and there is no foreign currency exchange available. Please bring sufficient Japanese yen cash with you before departing Tokyo.
** English is not commonly spoken in Ogasawara, including by tour guides, accommodation staff, and restaurant staff. Using a translation app is highly recommended. Most tours included in this package are conducted by Japanese-speaking guides.
** Diving tours may be canceled due to poor sea or weather conditions. If a tour is canceled, the fee will be refunded after the trip.
** We strongly recommend that customers arrive in Tokyo at least one day prior to the tour date, as the Ogasawara Maru ferry operates only once every 6 to 7 days. Please note that if you miss the ferry for any reason—including transportation delays or cancellations—the tour fee will not be refunded.
