- Water handling
- The facility, town and Yamaguchi Onsen Association confirm the natural-spring facility and its classification, but do not republish the full 2026 pool-by-pool supply. A town notice dated 31 January 2025 described a partial-restoration setup: spring water in the open-air black bath and tap water in the other pools. Confirm current supply with the facility before travelling specifically for the spring. Current per-pool water addition, heating, circulation and disinfection conditions are not confirmed.
Bathing indications
The town and tourism sources list general bathing information for a strong chloride spring. The spring classification is not a promise of personal health or cosmetic results.
The 2025 town notice describes spring water in the open-air black bath and tap water in the other pools at that time. Current pool-by-pool conditions have not been reconfirmed in the reviewed official pages.
The facility is operating, but reopening and normal operations do not by themselves confirm that every pool has resumed spring-water supply. The warm-water walking pool is currently listed as unavailable. Family baths are reserved for guests with care needs, older guests, people with disabilities or visitors accompanied by a child under 1; confirm eligibility and booking requirements.
