Hokkaidō Koma-ga-take (北海道ほっかいどう駒ヶ岳こまがだけ, Hokkaidō Koma-ga-take), also Oshima Koma-ga-take (渡島ととう駒ヶ岳こまがたけ), Oshima Fuji (渡島おしま富士ふじ), or just Koma-ga-take (駒ヶ岳こまがたけ) 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]
