Mt. Mihara 三原山

An active volcano in Tokyo

Mt Mihara forms the center of Izu Oshima Island . Rising 758 meters above the surrounding landscape the volcano was revered by residents for thousands of years as a sacred site. Although the volcano is active and erupts periodically every 30 to 40 years, the site is carefully monitored, and is a popular hiking spot.

Quick Facts

Hiking trails abound

How to Get There

During busy seasons there are regular buses to the trailhead from the port. Reaching the summit takes 45 minutes on foot from Mihara-sanchoguchi Bus Stop.

Dramatic, not dangerous

This dramatic site has been referenced multiple times in Japanese fiction, including where the Japanese government supposedly imprisoned Godzilla. Visit for yourself and discover a volcanic landscape quite unlike the other Tokyo Islands .

See the Urasabaku, a field of black sand created by the lava spat out by the volcano during its eruptions.

Ohachimeguri hiking trail runs around the crater and makes for a dramatic walk. Upon completion of your journey, relax at the Miharayama Onsen hot spring baths.
