Genki Mura Onsen House, also in Myōkō, Niigata Prefecture, offers sulfurous water at 44°C in a region well known for its onsen, an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Genki Mura Onsen House serves the Myōkō Kogen highland community in the Niigata volcanic zone where the active Myōkō volcano (2,454m) provides the geothermal heat driving some of Japan finest sulfurous mountain springs. The Myōkō highland was historically significant as the location of temples serving the Sado Island gold rush pilgrimage corridor, and the highland community of farmhouses and ryokan that grew up around the Myōkō volcanic springs has maintained a distinct mountain spa identity preserved under deep powder snow from November through April.
