A sodium-magnesium bicarbonate spring of the jūsō-sen style — mildly alkaline and soft on the skin, moderately mineralized with noticeable body. It sits squarely in Japan's beauty-water family, and a generous 228 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards. The certificate records fine black particles settling out of the sample about five hours after collection, a quiet hint of how much mineral matter the water carries.
