Kume, Matsuyama, Ehime Prefecture
Higashi Dogo Kume-no-Yu
A long-hour natural-spring bath close to Kume Station, with sauna included in admission. The operator reports circulation and filtration for the facility overall, so its source-flow description for the outdoor bath should not be extended to every pool.

Spring & water temperature
- Spring-source temperature
- 39.8°C for sources No. 6 and No. 8.
- Bathing temperature
- No fixed temperature is published. Ehime tourism describes the outdoor bath at about 40°C, not every pool.
- Spring source
- Higashi Dogo Onsen sources No. 2, No. 3, No. 6 and No. 8.
- Spring classification
- Alkaline simple spring; low-tonicity, alkaline and high-temperature category.
- pH
- 9.06 for sources No. 6 and No. 8.
- Flow rate
- Not published.
- Water handling
- The operator says no water is added, the water is heated to maintain a suitable temperature, circulated and filtered, and disinfected with chlorine-based chemicals. The operator's overall treatment description differs in scope from the Ehime tourism page's source-flow claim for the outdoor bath; do not label every pool source-flowing. Spring water is also used at the wash-station taps and in the cold bath.
The source analysis applies to sources No. 6 and No. 8; the outdoor-bath temperature is an approximate description, not a fixed setting for the full facility.
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.
