Short answer
A Chofu-to-Oshima flight with a Tokai Kisen high-speed jet ferry return can be one of Tokyo’s most satisfying transport-fan day plans. The aircraft gives you the 25-minute island-air experience; the jet ferry gives you the sea approach back to central Tokyo. It works best when you keep baggage light, reserve both legs, check same-day operation status, and avoid building the plan around a single fragile connection.
Last checked: August 21, 2026. Flight times, ferry times, fares, reservations, baggage rules, ports, weather decisions, and same-day operation status can change. Always confirm current details on New Central Airservice, Tokai Kisen, UMISORA, and official local sources before travel.
Why this combination works
Oshima is the easiest Chofu island flight to turn into a mixed transport day. UMISORA describes Oshima as less than two hours by high-speed jet boat and about 25 minutes by plane. That means the island is close enough for a compact itinerary, yet different enough that the air and sea legs feel like two separate experiences.
The best version is not “collect a plane and a boat at any cost.” It is a realistic route-choice plan: Chofu Airfield in the morning, Oshima by small aircraft, a few hours on the island, then a reserved high-speed jet ferry back to Tokyo Takeshiba if the sea service and your exact date fit.
Outbound by plane
New Central Airservice lists a Chofu-Oshima route on its official timetable and fare page. At the time checked, the regular adult one-way fare was 13,800 yen, the child one-way fare was 9,700 yen, and the adult round-trip fare was 25,100 yen. Those are checked planning facts, not permanent fares.
Use Chofu as the real beginning of the trip. New Central Airservice’s airport guide lists Chofu Airfield at Nishimachi 290-3, Chofu City, Tokyo, and says Chofu Station north exit is about 15 minutes away by Odakyu Bus. Its user guide says check-in is from 60 minutes before departure to 30 minutes before departure, and procedures should be completed 30 minutes before departure.
The flight is short, but the rules are not casual. The baggage page says free baggage is 5 kg per passenger, including carry-on and checked baggage. At the time checked, Chofu-Oshima excess baggage was listed at 240 yen per kg, but excess baggage may still be refused depending on the situation. Keep this as a light-pack plan.
Return by high-speed jet ferry
Tokai Kisen’s official English site lists high-speed jet ferry information for the Tokyo islands, and its English timetable PDF checked for this article included Tokyo-Oshima and Oshima-Tokyo services. In the checked September examples, Oshima return departures to Tokyo included 14:55 arriving 16:40, 15:15 arriving 17:00, and 15:50 arriving 17:35 depending on service code and date.
That return window is the reason this mixed plan can work. A morning aircraft leg can leave room for lunch, a short walk, a rental-car or bus-based stop, and a late-afternoon sea return. But the exact ferry must be matched to the exact date. Tokai Kisen’s PDF says all seats in all classes are reserved seats, so make a reservation.
Tokai Kisen’s reservation guidance says telephone reservations are accepted from two months before departure, and the timetable PDF says reservations can be made from midnight two months before the desired travel date until one hour before scheduled departure. For a day trip, do not treat the ferry as a walk-up safety net.
Baggage decision
This itinerary is friendly to small bags and unfriendly to bulky gear. New Central Airservice’s 5 kg free-baggage rule is the tightest part of the air leg. Tokai Kisen’s high-speed jet ferry baggage page allows two pieces per person within the listed free standards, but it also says the jet ferry has a compact design and cannot carry large or heavy baggage beyond the standards.
Tokai Kisen lists 1,200 yen one way for larger baggage within its charged range and 1,200 yen one way for a surfboard or bodyboard, while long boards cannot be carried aboard the jet ferry. The timetable PDF also warns that large cooler boxes over 30 L are not permitted on the high-speed jet ferry. If your Oshima trip needs heavy camera gear, camping gear, fishing gear, or a cooler box, this mixed day plan may be the wrong format.
Weather and status checks
This plan has two weather-sensitive legs, not one. New Central Airservice’s status page covers the Chofu-Oshima flight route. UMISORA’s Oshima pages show island access and operation-status context. Tokai Kisen publishes timetable and reservation information, but ship times and ports can still be affected by weather and sea conditions.
GO TOKYO’s island-access guide notes that travel times are for normal conditions and may vary with weather, and it directs travelers to operator websites for details. The practical reading is simple: check flight status, check ferry status, and keep enough time between island activities and the ferry pier.
Sample decision table
| Question | Use the mixed plan if… | Do something else if… |
|---|---|---|
| Do you want both aircraft and sea travel? | The transport experience is the point of the day. | You only need the fastest simple round trip. |
| Can you pack light? | Your bag is near New Central’s 5 kg free limit. | You need bulky gear, a large cooler, or heavy luggage. |
| Can you reserve both legs? | You have a confirmed flight and a confirmed jet-ferry seat. | You are relying on same-day availability. |
| Is the weather stable enough? | Both operator status pages look workable before departure. | Either leg is conditional, cancelled, or too uncertain. |
| Is your island plan modest? | You are happy with a focused lunch, walk, viewpoint, or short transfer. | You want a full island tour without timing pressure. |
Planning sequence
- Pick your exact date and check New Central Airservice’s Chofu-Oshima timetable.
- Check Tokai Kisen’s Oshima-to-Tokyo return options for the same date.
- Reserve the flight and the ferry before locking island activities.
- Keep baggage small enough for the aircraft first, then check jet-ferry baggage rules.
- Confirm how you will move between Oshima Airport, your island stop, and the departure port.
- Refresh New Central Airservice, Tokai Kisen, and UMISORA status on the travel day.
