- Not published for this facility. Older figures around 60°C and 52°C are not treated as current 2026 values.
- Bathing temperature
- Not published as a fixed setting.
- Spring source
- More than one spring. Nanyo Tourism names Morinoyama and Eboshi springs; the current association list for Akayu Onsen names Morinoyama, Morinoyama No. 2 and Yukawara. The 2026 source-name mapping for this individual bath is unresolved.
- Spring classification
- Multiple sources. The Morinoyama system includes a sulfur-bearing sodium-calcium chloride spring, but a current analysis covering the other source used here was not confirmed.
- pH
- Not confirmed for the current facility sources.
- Flow rate

- Water handling
- Nanyo Tourism describes the bath as using two springs. Current first-party information does not confirm all pool-by-pool details for water addition, heating, circulation and disinfection, so the baths are not described as entirely source-flowing.
