Futamata Radium Mineral Spring (artificial hot spring)
An artificial hot spring made lavishly with precious natural travertine stone from Futamata Radium Onsen, a hidden gem in Hokkaido. Rich in calcium carbonate and natural minerals, it gently warms the body from within, promotes blood circulation, and is effective in relieving neuralgia and sensitivity to cold. You can enjoy it in an elegant and very spacious indoor bath, as well as in the signature open-air bath, which boasts overwhelming scale and overlooks the mountains of the Taisetsuzan range.
