A simple thermal spring drawn from the "Yoshimatsu Kawahigashi No. 5" source in Tsurumaru, Yusui. The water emerges hot at 62.5 °C and is mildly alkaline, soft on the skin, with a faint pale-yellow tint. It is unusually rich in metasilicic acid (170.5 mg/kg), which leaves the kind of silica film that makes skin feel noticeably smoother and places it squarely in Japan's beauty-water family.
