Owakudani Onsen Steam-Generated Blended Spring (Lines 2 & 3)Operated by · 山田家 さくら(3F)
Mixed source
A steam-generated blended spring fed by the volcanic vapours of Hakone's Owakudani — a hot (source 60.6 °C) acidic calcium sulfate-chloride water. At pH 2.1 it is strongly acidic, sharp enough to sting slightly on contact and long associated with stubborn skin conditions. The water is slightly milky white with a faint hydrogen sulfide note, and a generous 157 mg/kg of metasilicic acid leaves a thin silica film that makes skin feel noticeably smoother.
