Tokyo's New Luxury, found in Tama and the islands of Tokyo

Motomachi Port or Okada Port

Oshima can be accessed via two ports: Motomachi or Okada. The day’s arrival port is determined each morning depending on the wind direction and waves. Taxis, rental cars, and transport to hotels will be waiting when you arrive at the port.
Buy Oshima’s special lunch box Shima-shima-bento from the shop at the port terminal and start touring the island!

Geological Strata

This geological cross section is now one of the highlights of Oshima. The guide will recommend the best angles for taking great photos. The layers, which give the impression of a ring-shaped layer cake, have formed through 20,000 years of Oshima’s volcanic history. Look up at the formation as your guide tells you how Oshima was formed.
The colors of the strata are different depending on the time of day and weather. Let your guide show you where to stand for your own one-of-a-kind photo opportunity.
If the weather cooperates, you’ll get a great view of the Izu Islands across the ocean.

Mt. Mihara Summit

The highlight of any sightseeing trip to Oshima! The path from the top of Mt. Mihara is paved, so even those who are unsteady walking on mountains can feel the wonders of the volcano. You won’t go all the way to the summit of Mt. Mihara on this trip, but you will walk as the guide explains the lava flow and plants in the area.
You can also enjoy learning about the smooth pāhoehoe lava, the bumpy ′a′a lava, and other volcano-related terms that originate from the Hawaiian language. Your imagination will grow as the guide explains where the lava came from after the eruption, how it flowed, and how it hardened. The story of the sturdy plants that have grown from the lava is also fascinating. Be sure to take a chance next time to climb to the summit and the crater! Your guide was born and raised in Oshima and can tell you all about the previous eruptions.

Motomachi Port or Okada Port

Oshima can be accessed via two ports: Motomachi or Okada. The day’s arrival port is determined each morning depending on the wind direction and waves. Taxis, rental cars, and transport to hotels will be waiting when you arrive at the port.
If you’re planning to spend a night on Oshima and not in a rush, we recommend having local specialties such as Bekko-don or seafood ramen for lunch at restaurants around Motomachi or Okada Port’s terminal before you start touring the island.

Geological Strata

The strata, which change color depending on time and weather, cannot be seen from up close for safety reasons.
You can see its real color by touching the same volcanic ash from the strata prepared by a guide.

This sign, which is shaped like a ring-shaped layer cake, is at the closest bus stop to the strata. It’s easy to miss, but its playfulness makes the trip more fun.

Habu Observation Deck

Habu Port, a round inlet visible from this observation deck, was the caldera of an old volcano.
It was once so popular for its wonderful breezes that you couldn’t walk around the port without bumping into someone.

Habu Port

Enjoy a guided tour of historical sites across the old caldera, including Jinnomaru Dwelling, the former residence of a fishermen’s boss, and the former inn Minatoya Ryokan, which is featured in a renowned Japanese novelist Yasunari Kawabata’s work, “Izu no Odoriko (The Dancing Girl of Izu.”)
The guide will explain the history of the port town road that gives a sense of just how round the caldera is, and the buildings with their old lattice work still intact.

As you walk along Habu Port you can try local favorites such as taiyaki fish-shaped pancakes sold from a refurbished old folk house, and deep-fried croquettes that are very popular among the locals. Having a guide familiar with the shopkeepers will make chatting with them even more enjoyable.
