Spring classification

Not published or confirmed. Current official pages confirm a natural spring called Ishikiri Onsen, but the main available text pages do not provide a complete legal classification or analysis figures. Older third-party classifications are not treated as current confirmed data.

Water handling

The current official site confirms that the public baths and outdoor bath use natural Ishikiri Onsen. The 2026 main official text pages do not fully disclose water addition, heating, recirculation or disinfection for each bath, so no overall free-flow claim is made. Older reviews and third-party details are historical references only.

Analysis date

Not published

Day-use bathing runs 06:00–23:30. Group bookings may restrict public access. Ishikiri Station is about a 5-minute walk away; Shin-Ishikiri Station is about 15 minutes on foot. The FAQ says station pick-ups must be requested in advance. The current main official pages do not confirm the tattoo policy. Older onsen records are not used to fill gaps in current spring classification, temperature or water-treatment data.
