Mt. Tomuraushi is an independent lofty mountain with an altitude of 2141 m located on the border of Biei-cho, Kamikawa-gun and Shintoku-cho, Tokachi-gun in Hokkaido. It is on the edge line connecting Mt. Taisetsu and Mt. Tokachidake. The word “Tomuraushi” means “the place full of flowers” or “the place with a lot of water stains” in Ainu. It is selected as one of Japan’s 100 Fine Mountains. This rocky mountain is called “the inner sanctum of Taisetsu,” where there are full of alpine plants and beautiful ponds and lakes. As it takes a long time to get to the summit from any of the starting points of climb, only experienced climbers could visit this “far mountain” until some time ago. On the way to the summit, there are a lot of unspoiled natural features such as a pond reflecting the reverse image of the mountain or a huge field of flowers at Goshikigahara. Mt. Tomuraushi is a mecca for climbers.
