UtaseyuAbout
KAMENOI HOTEL KOCHI stands on the bank of the Niyodo River in Ino, and its baths run on salty, skin-soft onsen water: a large indoor bath, a reclining bath, and an open-air bath that looks out over the river, with trains crossing a bridge on the Dosan Line in view. There's also a waterfall bath (utaseyu, 打たせ湯) and a foot-pressure-point corner. It's a quiet onsen hotel by the river, built around a spacious restaurant and the large communal bath. Some guest rooms have their own bath, but it runs plain hot water rather than the onsen supply.
