About
A day-use natural hot spring facility on a hill near Minami-Tama Station on the JR Nambu Line (5-min. walk) and Inagi Station on the Keio Sagamihara Line (7 min. by bus). It opened in November 2007 and reopened after renovation on December 14, 2023. A mildly alkaline sodium bicarbonate-chloride spring, drawn from 1,700 meters underground, feeds an open-air rock bath directly from the source. The indoor baths include two carbonated baths: a hot-spring carbonated bath and a Phiten-technology carbonated bath. Two saunas are available: an automatic-löyly dry sauna and a herb-and-mud steam sauna. The paid rock-bath area features a room with a music-synchronized löyly show and its own outdoor relaxation terrace. Visitors with tattoos or body art are not admitted.
