A hot (61 °C) chloride-sulfate spring led by calcium and sodium, drawn from the Tsushima No. 22 well. Weakly alkaline (pH 8.4) and soft on the skin, with a moderate 3.05 g/kg of dissolved solids that gives the water noticeable body. Metasilicic acid at 52 mg/kg adds a faint silica-film smoothness — the kind of finish that places it gently in the Japanese 'beauty-water' family.
