Spring & water temperature
- Spring-source temperature
- Not published as a current value; the 18.2°C figure is from a 2009 analysis.
- Bathing temperature
- Not published.
- Spring classification
- Natural black-water spring. Historical 2009 analysis lists pH 8.0 and source temperature 18.2°C; these are not current 2026 analysis values.
- pH
- Not published as a current value; the 8.0 figure is from a 2009 analysis.
- Flow rate
- Not published.
- Water handling
- Edogawa City explicitly identifies the outdoor bath as source-flowing black water and the cold bath as spring water. This does not establish source flow in every pool.
Do not confuse the outdoor bath's confirmed source-flowing status with an all-pool source-flow claim.
How to read a bath profile
Spring-source temperature and actual bathing temperature are kept separate. Each score is shown independently for comparison rather than collapsed into one overall score.
