Shikaribetsu Kohan Onsen sits on the shore of Lake Shikaribetsu in Hokkaido's Kato District, where sulfated thermal waters are enjoyed against the backdrop of one of Japan's most scenic caldera lakes—ringed by forests and mountains that turn fiery in autumn and freeze dramatically in winter under Hokkaido's extreme cold. Lake Shikaribetsu is famous for its winter ice village, where the lake's frozen surface becomes a venue for temporary thermal bathing structures built directly on ice, creating an extraordinary contrast between extreme cold and volcanic warmth unique to Hokkaido's winter onsen culture. The lakeside setting and sulfate-rich mineral composition make Shikaribetsu Kohan an exceptional destination at the intersection of natural spectacle and a long thermal bathing tradition.

Insider tip — Shikaribetsu Kohan Onsen sits on the shore of Lake Shikaribetsu, Hokkaido's highest-altitude lake and one of its most scenic, where calcium-sulfate waters have been drawing visitors since the Meiji era. In winter, the frozen lake hosts a famous ice village with igloo accommodations and outdoor baths steaming in sub-zero temperatures — a uniquely Hokkaido experience. The surrounding Tokachi highlands offer excellent cross-country skiing and snowshoeing. Summer visits reward guests with crystal-clear lake reflections of forested volcanic peaks.
