About

KKR Minakami Suimeiso (KKR水上水明荘) sits beside the Tone River in Minakami's Yuhiroso (湯檜曽) hot spring area. The open-air bath looks out over the river through the changing seasons, and a barrel sauna with a cold plunge and outdoor chairs shares the same space. There is also an indoor large bath and a free private family bath available to all guests. The spring water is clear and gentle on the skin.
