👉 Travelers looking for the cheapest way to visit Izu Oshima from Tokyo.
The overnight ferry is popular because:
👉 Even a weekend 2-day trip feels surprisingly full and relaxing.
In this guide, I’ll share my real experience using the ferry, including booking tips, access information, onboard facilities, what the 2nd class cabin is really like, and useful items that made the trip much more comfortable.
The Sarubia Maru is a large overnight ferry operated by Tokai Kisen connecting Tokyo and the Izu Islands.
The ferry departs from Takeshiba Passenger Terminal at night and arrives at Izu Oshima the next morning.
One of the best parts of the trip is sailing through Tokyo Bay at night while passing under the Rainbow Bridge.
👉 The ferry itself feels like part of the adventure — not just transportation.
Because you travel overnight, you can sleep during transit and start exploring the island immediately after arrival.
You can reserve tickets online through The official Tokai Kisen website.
Available options include:
👉 During busy seasons (summer holidays, long weekends, New Year), booking 1–2 weeks early is highly recommended.
⚠️ Ferry schedules and prices may change depending on weather and season.
Access from central Tokyo is easy:
💡 I recommend arriving at least 30 minutes before departure.

Night departure → morning arrival.
⚠️ Travel time may vary depending on weather and departure port.
👉 Sleeping during transportation makes the trip very time-efficient.
The ferry has surprisingly good facilities for an overnight trip.
⚠️ Wi-Fi only works near Tokyo Bay and is mostly unavailable offshore.

Available cabin options include:
👉 If you want the best balance between comfort and price, the 2nd class Japanese-style cabin is the best option.
As of March 2026:
2nd Class Chair Seat
Special 2nd Class Cabin
The 2nd class cabin is a shared Japanese-style sleeping area.
At first, the “sleeping together on the floor” style may sound uncomfortable, but honestly:
👉 It’s much better than expected.
You can fully lie down during the overnight trip, which makes a huge difference compared to sitting in a chair.
2nd Class Japanese-style Room
👉 Overall: absolutely sleepable and good enough for budget island travel.
Overnight ferries are all about sleep quality.
These items made my trip much more comfortable.
The onboard pillows are quite hard and high.
👉 Bringing your own travel pillow is highly recommended.
Especially important in shared sleeping rooms.
Power outlets are limited.
Useful against sea wind and strong onboard air conditioning.
Very convenient when moving around the ship at night.
These two items make a surprisingly big difference.
