Simple
Classification
Sodium Chloride-Bicarbonate spring
An alkaline simple thermal spring at pH 8.9, sitting in the Japanese beauty-water family with the characteristic slippery feel. Mineralization is light (289 mg/kg dissolved solids), so the 56 °C source reads as gentle and easy to soak in rather than mineral-heavy. The water itself is nearly colourless, tasteless and odourless — the appeal is the soft, smooth feel on the skin rather than any sensory signature.
