15. Okunoyu, Kurokawa Onsen ★★★ Visited on a day trip. This ryokan with a mixed-gender rotenburo is located east of the central area of Kurokawa. Day-use is usually available from 08:30 to 20:00 and from 15:30 to 20:00, sometimes only on certain weekdays. It is part of the Kurokawa tag. Day users are allowed access to the main mixed-gender outdoor bath and the adjacent indoor single-gender bath. Guests staying overnight have access to another indoor bath and three private baths. The ryokan provides its own branded towels. 1. Large mixed-gender outdoor bath area. Amazing view of the forest, river, and waterfall. Due to the elongated architecture of the baths, the view of nature is wide and even more impressive. 1.1. Large main stone bath. The water is clear with a slightly cloudy white-green tint. Temperature about 42°C. 1.2. Cave bath with a view. Water temperature about 39°C. 1.3. Small distant stone bath with a view of the waterfall.
