A sodium-led bicarbonate spring with a chloride sub-type — the classic jūsō-sen (soda-water) style, soft and smooth on the skin. With neutral pH and a generous 124.6 mg/kg of metasilicic acid, it sits squarely in Japan's beauty-water family, leaving the kind of silica film that makes skin feel noticeably smoother. Moderately mineralized at 1,274.6 mg/kg of dissolved solids, the water is colorless, transparent and odorless.
