Classification
Sodium-Magnesium-Calcium Bicarbonate spring
A sodium-magnesium-calcium bicarbonate spring, rising at 47 °C from the wellhead. Weakly alkaline and soft on the skin, it sits in the Japanese beauty-water family. A generous 201 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards.
