Spring & water temperature

- Not published in the current material summarized here.
- Bathing temperature
- Not published as a fixed setting.
- Spring source
- Two springs used separately: Azero-yu and Shibagaki-yu.
- Spring classification
- Azero-yu: sodium chloride spring. Shibagaki-yu: sodium chloride and bicarbonate spring.

- Not published.
- Flow rate
- Not published.
- Water handling
- The inn offers the two springs in separate baths. It cools the hotter Azero-yu with a cooling tank and tries to adjust the temperature without adding water. Current main pages do not fully publish heating, circulation or disinfection conditions for each pool, so those details are not inferred.
Bathing indications
No specific medical effect is claimed here.
The two spring waters are kept separate. The hotter Azero-yu is cooled in a holding tank, with water addition avoided where possible; other treatment details are not fully published.
Regular admission is ¥270 for adults and ¥80 for children. A private bath costs ¥1,500 for 60 minutes, with an additional ¥500 for up to 30 more minutes. Tattoo rules are unconfirmed.
How to read a bath profile
