Owakudani Onsen Steam-Generated Mixed Spring (Line 2 / Line 3)Operated by · 万寿屋旅館
Mixed source
An acidic calcium sulfate-chloride spring generated from the volcanic steam of Owakudani. At pH 2.1 the water is sharp enough to sting slightly on contact, faintly milky-white and turbid, carrying a faint rotten-egg note of H₂S. It is well supplied with metasilicic acid at 157 mg/kg, leaving a thin silica film for noticeably smoother skin. It is served as untreated source flow — no dilution, heating, recirculation, or disinfection.
