A blend of three wells — Mitsui Kinzoku No.1, Kannon and Tenyu — sampled not at a wellhead but at the mixing-tank outlet, after dilution. Bicarbonate accounts for 81% of the anions, yet with only 0.86 g/kg of dissolved solids the certificate files it as a simple thermal spring, hypotonic and neutral at pH 6.4. It leaves the ground at 67.7 °C, among Japan's hotter natural sources, faintly yellow and clear with pale yellow-white flecks drifting in it. Metasilicic acid at 153 mg/kg is generous enough to leave the thin silica film that puts this water in Japan's beauty-water family.
