About
Kuroyu Onsen keeps separate baths for men and women, each with an indoor bath, an open-air bath, and an utaseyu (打たせ湯, a small waterfall bath for the shoulders), plus a mixed-bathing bath and two reservable private baths, Kame no Yu (亀の湯) and Tamahada no Yu (玉肌の湯), free once per stay for overnight guests and paid for day visitors. The water is a simple sulfur spring, milky and faintly blue-white on the skin. It's the innermost ryokan of Nyuto Onsenkyo, at the head of the valley where spring water rises right along the riverbank on the grounds. Rooms are plain and unfussy, and people tend to come back more for the staff's warmth than for polish.
