Mt. Musa (武佐岳, 1,005m) is a volcanic mountain standing as advance guard to the more famous far-east mountains of the Shiretoko Peninsula in Hokkaido, Japan. As such, the summit provides panoramic views across the plains and close-by Pacific Coast to the east, and peaks such as Mt. Shari (斜里岳, 1,547m) and Mt. Rausu (羅臼岳, 1,660m) to the northeast. En-route is the extremely rustic, half-derelict Mt. Musa Sokuseiso Hut. Dense low-lying trees prohibit skiing directly from the summit, but there are some skiing options from the ridge further down.
