A sodium-led bicarbonate-chloride spring, with calcium and magnesium filling out the cation side. Weakly alkaline and soft on the skin, it sits in jūsō-sen (soda-water) territory and squarely inside Japan's beauty-water family. Moderate mineralization of 1,347 mg/kg gives the water noticeable body, while metasilicic acid runs to 156 mg/kg — the kind of silica load that leaves a thin film and makes skin feel smoother afterwards. This certificate was sampled at the bath inlet rather than the wellhead, so the readings describe the water as it actually reaches bathers.
