From the printed spring name, this ryokan's water can be read as Chloride Spring and Sulfate Spring. We have not yet collected the measured values (minerals, pH) from an analysis report.
- Chloride Spring
- Feel
- Tastes salty; the warmth lasts after you get out.
- Said to
- Salt is said to form a film on the skin that keeps in heat and moisture. Bathing indications include cuts, poor circulation and dry skin.
- Note
- May sting cuts. Strong salty water can tire you—avoid long soaks.
Effects are general descriptions based on the Ministry of the Environment’s indications by spring type, not a guarantee.
