The facility was opened in a natural forest spread on the banks of the Kinu River on the outskirts of Shimotsuma City. It sells local beer and fresh local vegetables in the lobby shop, mainly in one-day hot spring facilities, and in the accommodation building with 19 rooms. The bathhouse is followed by a whirlpool or bubble bath, a sleeping bath, a large bathhouse with a sauna, and an open-air bath with a Tōya-style roof outside. The two large baths are a daily change of gender. There is also a large hall of 100 tatami mats after taking a bath, so it's okay for a group.
