Izu Oshima Island is located approximately 120 km south of Tokyo and can be reached via boat/ferry.

TOKAI KISEN is the ferry boat company that provides all of the transportation between Tokyo (mainland Japan) and the Toyko Islands including Oshima Island.


In order to make it to the event for the 6 hour category on time, you will need to leave Tokyo on Friday.

Those who participate in the 4 hour category can take early morning ferries on Saturday.

Please see below for the 2 options recommended in order to make it to the start of the event.


Option #1 - High Speed Jet Ferry


High speed jet ferries leave Takeshiba Port (about a 10 minute walk from the JR Hamamatsusho train station in downtown Tokyo). Departures also from Atami in Shizuoka.

Trip Duration: Approximately 2 hours

You will need to depart on Friday morning or afternoon as there are no ferries that arrive into Oshima on early Saturday morning.



Option #2 - Large Passenger Ship


Passenger ships depart at night (around 22:00) and arrives into Oshima at 6:00 am in the morning. This is a slower but fun way to enjoy the night views of Tokyo Bay! There are private rooms as well as shared rooms with bunk beds and/or floor space where you can sleep as well. You will need to depart on Friday night for this option. 




Arriving into Oshima:

There are two main ports in Oshima: Okada Port and Motomachi Port. The ships will arrive into one of these two ports depending on weather conditions that day.


If you take the large passenger ship, you will arrive into Oshima early on Saturday morning (6:00am). As there is a bit of a time until the race starts, you may want to wait and relax at the "Gojinka Hot Springs" facility in Motomachi. The hot springs is only a 3 minute walk from Motomachi Port and breakfast can also be purchased there.
