An acidic calcium sulfate-chloride spring generated from the volcanic steam of Owakudani. At pH 2.1 it is strongly acidic, sharp enough to prickle slightly on contact, and arrives slightly cloudy-white with a faint rotten-egg note of hydrogen sulfide. A generous 157 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards. The water is served as untreated free-flow, with no dilution, heating, recirculation, disinfection, or bath additive.
