Volcanic Miyakejima diving and carefully managed Mikurajima dolphin swims
Use this travel brief to set arrival flow, local transit, and gear movement before you lock your itinerary.
Miyakejima: Tokai Kisen operates an overnight passenger vessel from Tokyo Takeshiba Pier to Miyakejima. The Miyakejima Tourism Association lists a typical roughly 6.5-hour passage. Alternatively, New Central Airservice flies small aircraft from Chofu Airfield to Miyakejima Airport, usually about 50 minutes, not from Haneda. These services are weather-dependent. Mikurajima: Tokai Kisen continues south on its route after Miyakejima, but Mikurajima has only one exposed landing and boats may sail past without disembarking. The Tokyo Ailand Shuttle helicopter connects Mikurajima with nearby island airports and is capacity-limited and weather-dependent. A Mikurajima day trip on an ordinary ferry is not a reliable plan, and the tourism association says on-island accommodation must be prebooked. A qualified Miyakejima diving service may instead operate a separate dolphin-watching excursion into Mikurajima waters: this is not a scheduled public passenger transfer.
Miyakejima Airport
MYE • RJTQ
Island airport served by New Central Airservice small-aircraft flights to and from Chofu Airfield in Tokyo. No Mikurajima runway exists; Mikurajima uses its heliport for the separately operated island shuttle.
Transport: Prearranged guesthouse pickup, Island village bus where timetable and route fit, Prebooked rental car or taxi
Miyakejima: A village bus circles districts; rental cars, limited taxis and assisted bicycles are listed by the Tokyo Metropolitan Government. Coastal sites are spread out and the actual ferry landing can switch among three ports, so arrange early-morning transfers and equipment transport in advance. Mikurajima: There is no public car rental or bicycle use for tourists; the compact village is walkable, with lodge or boat crew pickup from the harbor. Most hiking beyond town requires a certified nature guide. Arrange transport on each island separately; regional map coverage does not establish a passenger connection.
Both islands are in Japan; national immigration rules apply on arrival to Japan, with no separate island immigration visa. Check your nationality and passport with the Japanese Ministry of Foreign Affairs and your point of arrival. Mikurajima visitor access has additional practical requirements: the local tourism association says a confirmed accommodation reservation is essential before landing and prohibits camping. Public dolphin-watching boats operate under local environmental controls and Tokyo-certified guiding arrangements. An ordinary ferry ticket alone is not sufficient to assume a Mikurajima stay.
Bring any unusual scuba fitting or freediving gear from Tokyo, and book tanks, weights, appropriate cylinders, suit sizes and guide service with a Miyakejima operator beforehand. The Miyakejima tourism office says purchasing snorkeling gear locally is very limited. For Mikurajima dolphin boats, ask about fin, mask, wetsuit, flotation, camera and luggage restrictions; a 2026 operator specifically revised boat prices, so check fresh quotes. Pack for exposed small boats and overnight weather delays, with medications and essentials in your hand luggage. Confirm New Central Airservice and helicopter baggage rules separately.
Japanese Yen (JPY)
Both islands use Japanese yen. Cards are accepted at some Miyakejima providers, but Mikurajima guesthouses and stores can be cash-oriented and the island tourism association advises cash planning. Pay locally in yen; no USD or EUR settlement should be assumed.
Mikurajima has a post-office ATM with hours and card network acceptance to confirm before arrival; access is restricted by island hours and weather. Miyakejima tourism lists postal and local financial-institution ATMs. Carry enough yen for lodgings, tours, transfers and a possible unplanned weather night.
100V • 50Hz • A
Eastern Japan uses 100V, 50Hz electricity with Type A outlets as the usual travel standard. Use a compatible dual-voltage charger and adapter for foreign plug shapes; do not assume a 230V-only appliance will work.
Communications
Mobile service is generally usable in Mikurajima village and much of Miyakejima's settlements, but mountain interiors and open ocean may lack reliable coverage. Mikurajima tourism lists Wi-Fi at some lodges and its visitor facility. Download offline maps, ferry information and Japanese-language booking details before boarding, and keep a local operator contact number written down.
Language
Japanese is the working language for ferry changes, local clinics, guesthouses and most licensed boats. Some dolphin operators provide English guidance, but not every boat, lodging or nature guide does. Ask in writing whether safety briefings and emergency instructions are available in a language you understand. Keep key phrases and allergy/medical information in Japanese.
Insurance
Choose cover that explicitly includes recreational scuba where relevant, guided open-ocean dolphin snorkeling and breath-hold swimming where relevant, remote emergency medical evacuation and disruption caused by weather or transport non-landing. Check depth limits, pre-existing conditions, helicopter transfer exclusions, and trip interruption rules. A national healthcare access right or standard travel insurance card is not evidence of dive or evacuation cover.
Packing list
Bring a wind and rain shell, layers for wet boat rides, water shoes for sharp volcanic shores, reef-safe sun protection, personal prescription medication, seasickness strategy, a spare dry set for ferry changes and cash. For ocean sessions pack a proven mask, snorkel, fins and suitably warm wetsuit or arrange confirmed rental sizes. Binoculars help on Miyakejima; proper trail shoes are essential on guided Mikurajima forest paths. No flash or selfie-stick use on dolphin swims.
