Tenchozan

天頂山

Shari, Hokkaido / Rausu, Hokkaido · Elevation 1,046 m

Tenchozan (1,046 m) is a small andesitic stratovolcano straddling Rausu and Shari towns on the Shiretoko Peninsula in eastern Hokkaido. A row of fifteen-plus explosion craters runs 1.8 km along the active Rausu Fault across its summit, and the most recent activity was a phreatic eruption about 1,900 years ago. Japan recognized it as an active volcano on 7 June 2011. There is no maintained trail; ascents are typically snow-season climbs from Shiretoko Pass through dwarf-pine cover, within Shiretoko National Park.
