A sodium-led bicarbonate spring — the classic juso-sen style, neutral in pH and soft on the skin, with moderate mineralization of about 1,169 mg/kg dissolved solids. It sits squarely in Japan's beauty-water family: a generous 159.9 mg/kg of metasilicic acid, backed by 113.4 mg/kg of metaboric acid, leaves the kind of silica film that makes skin feel noticeably smoother afterwards. The certificate takes its sample at the open-air bath inlet rather than at the wellhead, so the figures describe the water as it actually reaches the pool.
