Kotohira Onsen Yume Sansui Open-Air Baths
Four stone open-air baths along the Takase River, with a separate 16-room family-bath area. The public baths are source-flowing; that treatment description does not automatically apply to the private rooms. A local bus timetable change takes effect on October 1, 2026.
Check before bathing
- Opening hours
- Public baths: weekdays 12:00–20:45 (last admission 20:15); weekends and holidays 11:00–21:00 (last admission 20:30). Adult ¥800, child ¥400; peak-period admission may be ¥1,000 for adults and ¥500 for children.

How to read a bath profile
Spring-source temperature and actual bathing temperature are kept separate. Each score is shown independently for comparison rather than collapsed into one overall score.
