Classification

Calcium-Sodium-Magnesium Bicarbonate spring

A lightly mineralized simple cold-mineral spring (21.5 °C at the wellhead) that qualifies as an onsen on its metasilicic acid content. Total dissolved solids are a modest 0.479 g/kg and the water is weakly acidic and gentle on the body. With 94.4 mg/kg of metasilicic acid it sits in the Japanese beauty-water family, leaving a thin silica film that makes skin feel smoother. A faint hydrogen sulfide note rises at the source.
