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