Tokachidake Onsen is a mountain hot spring in Kamifurano Town, Sorachi Subprefecture, Hokkaido, located at an elevation of 1,280 meters on the flank of Mount Tokachidake within the Daisetsuzan National Park, making the Ryoun-kaku inn at the spring the highest-altitude hot spring resort in Hokkaido. Mount Tokachidake is an active stratovolcano in the Daisetsuzan volcanic group whose eruptions in 1926 and 1988 are among the most significant volcanic events in twentieth-century Hokkaido history, and the sulfurous springs at Tokachidake Onsen are a direct product of the geothermal activity of this still-active volcanic system. The dramatic alpine setting, with panoramic views across the volcanic caldera and the surrounding Daisetsuzan peaks, combined with the intensely sulfurous waters of the high-altitude springs, makes Tokachidake Onsen one of the most adventurous and spectacular hot spring destinations in all of Hokkaido.
Insider tip — Tokachidake Onsen sits at 1280 m elevation on the active Tokachi volcanic chain in the Daisetsuzan National Park, one of Japan's highest and most accessible volcanic thermal resorts. The strong sulfurous spring emerges at high temperature with a milky-blue colour from dissolved colloidal sulfur particles. The outdoor bath faces a raw volcanic landscape of fumaroles and lava fields that remains snow-covered from October to late May. Dawn bathing in early winter, with the volcanic plume merging with steam from the pool against a star-filled Hokkaido sky, is an unforgettable sensory experience.
