Mt. Mihara 三原山

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.

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.

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.
