MountainsAbout
A hotel built like a small European castle, with a marble indoor main bath, a large open-air bath and a separate lookout open-air bath, plus a far-infrared dry sauna. The water is slippery and silky on the skin, and bathers often mention how smooth it leaves them. The lookout bath faces a river and mountains below. Day-use bathing (higaeri nyuyoku, 日帰り入浴) is open to non-guests, and the building also has a restaurant, a cafe and a bakery.
