Okutsu Onsen, Kagamino, Okayama Prefecture
Hanabijin-no-Sato, Okutsu Onsen
A strong choice for a facility-style day at Okutsu, especially if you want a 38–39°C warm bath, sauna and places to rest. If a private bath is essential, choose another facility until the family bath reopens.

- Water handling
- The facility offers indoor and outdoor natural-spring baths, Bijin-no-yu and jet baths. Its main current text pages do not fully publish water addition, heating, circulation or disinfection conditions for each pool. The silk bath uses ultra-fine bubbles; that feature is separate from the source-water treatment method.
Bathing indications
The facility publishes general bathing indications. The pH and “Bijin” name are not treated as a beauty or skin-treatment guarantee.
Use the facility's current rates of ¥940 for adults and ¥470 for children rather than older tourism listings showing ¥880 and ¥440. The family bath remains suspended even where older price information is still visible. The second-floor silk bath was reported closed on 2 September 2026; reopening had not been confirmed by 7 September. Special schedules may include Thursday openings or substitute closure days, so check current notices.
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.
