Hokkaidō Koma-ga-take (北海道駒ヶ岳 Hokkaidō Koma-ga-take), also Oshima Koma-ga-take (渡島駒ヶ岳), Oshima Fuji (渡島富士), or just Koma-ga-take (駒ヶ岳) is a 1,131 metres (3,711 ft) andesitic stratovolcano[1] on the border between Mori, Shikabe, and Nanae, all within the Oshima Subprefecture of Hokkaidō, Japan .
Occurrence of volcanic activity started some 30,000 years ago. Following roughly 5,000 years of dormancy, volcanic activity at Mount Koma-ga-take restarted in 1640,[2] triggering the Kan'ei Great Famine.[citation needed] Since then, there have been at least 50 recorded volcanic events at Mount Koma-ga-take.[3]
