- Water handling
- Miyazaki City's tourism page describes the outdoor bath as source-flowing and the cold bath as using spring water directly. The facility also says its private bath is source-flowing. Water addition, heating, circulation and disinfection conditions for the main bath are not fully published, so evidence for those specific baths is not extended to the entire large bath.
Bathing indications
The facility lists spring-specific indications including autonomic nervous-system instability, insomnia, atopic dermatitis and chronic eczema. These are not a treatment guarantee.
Current general admission is ¥700 for adults and ¥450 for children. The facility sets extra maintenance closure dates, so check its news before travelling. Tattoos and irezumi are prohibited.
