RiverAbout
This ryokan sits above the Iwai River gorge, and its open-air bath looks straight down over the water. Alongside the rotenburo there is an indoor bath, a sauna and a cold plunge, with both hotter and milder pools to move between. The baths run on a men's and women's swap schedule rather than mixed bathing. The water is drawn from the property's own onsen source, and day-use visitors can also have lunch at the in-house restaurant.
