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 1131-meter adesitic stratovolcano^[1] on the border between Mori, Shikabe, and Nanae, Hokkaidō, Japan.

Occurrence of volcanic activity started some 30000 years ago. Following roughly 5000 years of dormancy, volcanic activity at Mount Koma-ga-take restarted at the start of the 17th century. Since then, there have been at least 50 recorded volcanic events at Mount Koma-ga-take.^[2]
