Mt. Nishibetsu (西別岳, 741m) is a diminutive hill famous for its alpine vegetation despite its low altitude. Not much further north is the caldera rim of Lake Mashu (摩周湖), so Mt. Nishibetsu can be a good transit point for adventures further afield. In this route guide I introduce the hopelessly beautiful Nishibetsu Hut (西別小屋, 335m), only accessible in winter on skis or snowshoes via a 5km forestry road. This free hut, unlocked and open for use, is the perfect base to explore the area's winter offerings.
