A gentle simple thermal spring rising in Beppu's Shiomi-machi district, weakly alkaline and lightly mineralized at just 0.4 g/kg of dissolved solids — soft on the body with very little bite to it. What lifts it above ordinary simple water is metasilicic acid at 175 mg/kg, generous enough to leave the thin silica film that places this water in Japan's beauty-water family and makes skin feel noticeably smoother afterwards. At the wellhead it runs faintly yellow but clear, carrying a very faint hydrogen sulfide note that has already faded by the time the sample reaches the lab.
