A hot 58.5 degree C blended sodium chloride, bicarbonate and sulfate spring. Weakly alkaline and soft on the skin, it sits in Japan's beauty-water family — the chloride base brings a salty edge, the bicarbonate adds softness, and the sulfate lends quiet body. Moderate mineralization (1,257 mg/kg dissolved solids) plus a generous 162 mg/kg of metasilicic acid leaves a thin silica film that makes skin feel noticeably smoother afterwards.
