Kotohira Onsen Yume Sansui Family Baths
Sixteen private rooms span seven bath styles, with four public riverside baths on the same site. The family baths have window views of greenery, but the operator does not identify all 16 as open-air; confirm a specific room if that matters.

Bathing indications
The operator lists general bathing indications including neuralgia, muscle and joint pain, stiff shoulders, limited mobility, bruises, sprains, chronic digestive conditions and sensitivity to cold. These are facility-published indications, not a promise of medical benefit.
The site also has four public riverside open-air baths. A family bath's window view does not establish that it is open-air.
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.
