Takeyama Kogen Onsen is located on the island of Hokkaido, northern Japan, a volcanic territory rich in hot springs. Sulfurous water emerges at 44°C, with an indoor bath, an outdoor rotenburo, and a sauna.
Insider tip — Takeyama Kogen Onsen sits on the Ishikari volcanic plateau in central Hokkaido, where subterranean heat pushes sulfurous water to the surface at high temperature. The highland setting at several hundred metres elevation keeps summer temperatures refreshingly cool while the hot baths warm you from within. Clear skies at this latitude offer exceptional stargazing from outdoor pools on clear nights. The surrounding plateau is excellent for cycling and wildlife watching in the warmer months.
