Kawayu Hot Spring
Volcanic Power, Winter Magic, and One of Japan's Most Unique Hot Springs
Nestled by active Mt. Io in Akan-Mashu National Park, Kawayu Onsen is famous for its rare highly acidic waters. In winter, visitors can witness the magical Diamond Dust phenomenon shimmering in the air.
Kawayu Onsen is one of Hokkaido's most distinctive hot spring towns, located at the foot of active Mt. Io (Sulphur Mountain). Its unique waters are among the most acidic in Japan, with a pH of 1.6 to 1.8. Created by the volcanic forces of Mt. Io, these waters offer an invigorating sensation and a refreshing feel on the skin. Long favored by travelers seeking the raw energy of the earth, this remarkable hot spring provides an authentic bathing experience.
The town features several free-flowing footbaths where visitors can enjoy the warm waters while wandering through sulfur-scented streets. In winter, the rare Diamond Dust phenomenon may appear, with tiny ice crystals sparkling as they drift through the crisp air. Surrounded by the dramatic volcanic landscapes of Akan-Mashu National Park, Kawayu Onsen offers the perfect way to relax and recharge while experiencing one of Hokkaido's most unforgettable natural settings.
