Muine-yama
↕ 1163 m · 2 Routes · Explore in 3D
Muine-yama is reported to have the largest number of avalanche fatalities of any mountain in the Sapporo region (per the Hokkaido avalanche research record) — steep east-facing slopes and deep, tight runout gullies are the main reason. Check the Japan Avalanche Network bulletin and choose slopes conservatively. Note also that the Muine-jiri hut (Hokkaido University writes it 「無意根小屋」) is out of use after a fire: the university notice reads 「令和6年11月火災により利用停止」. There is no usable shelter on this mountain — plan it as a day trip.
