A hot (48.4 °C) sodium-calcium bicarbonate-chloride spring — the classic 'jūsō-sen' (soda-water) style softened by a salty bicarbonate-leaning chloride sub-type. Weakly alkaline at pH 7.8, gentle on the skin, and sitting squarely in the Japanese 'beauty-water' family. The water carries only a faint yellow tint at the source with virtually no taste or odor. Unusually rich metasilicic acid at 233 mg/kg leaves the kind of silica film that makes skin feel noticeably smoother afterwards.
