Kawaguchiko Onsenji overlooks the shores of Lake Kawaguchi in Fujikawaguchiko, Yamanashi Prefecture, at the foot of Mount Fuji. Sulfurous water surfaces at 44°C, shared between an indoor bath and an outdoor rotenburo facing the lake. A sauna rounds out the bathing facilities.
Insider tip — Kawaguchiko Onsenji sits at the foot of Mount Fuji near Lake Kawaguchi, harnessing the volcanic geothermal energy of the Fuji Five Lakes region. The temple-adjacent bathhouse name Onsenji, meaning hot spring temple, reflects the deep intertwining of sacred geography and bathing culture in this area. Sulfurous waters here carry a mild milky opacity on high-activity days, a marker the Japanese call nyu-haku, or milk white. The lake and Mount Fuji views from elevated outdoor baths are among the most dramatic in the Kanto region.
