CityAbout
Sitting at the base of Mt. Myogi, this day-use facility has both indoor baths and an open-air rotenburo, with the rotenburo looking out over the rocky peaks of Myogi and the Kanto plain stretching below. There is also a sauna and cold bath. The facility is on the smaller side. An attached restaurant, Gozantei (御山亭), serves meals made with local ingredients and is open to non-bathers as well.
