Norikura Kōgen Onsen

Norikura Kogen Onsen is situated on the Norikura volcanic highland plateau in Nagano Prefecture at the foot of Mount Norikura, a volcanic massif that straddles the border between Nagano and Gifu prefectures and offers some of the most accessible high-altitude terrain in the Japanese Alps. The spring flows with bicarbonate and sulfurous thermal waters, combining the skin-conditioning alkalinity of carbonate chemistry with the potent therapeutic character of volcanic sulfur, a mineral pairing that reflects the active geothermal energy of the Norikura volcanic system. Set among the wildflower meadows and ski slopes of one of Nagano's most celebrated highland destinations, Norikura Kogen Onsen provides the ideal complement to a day exploring the volcanic plateau's abundant natural beauty in both summer and winter.
