Sodium Sulfate-Chloride spring
A private source serving Kurokawa Onsen Ryokan Wakaba. Hot at 70.1 °C (one of Japan's hotter wellheads) and weakly acidic at pH 3.7, yet the dissolved-solids load is light enough at 0.67 g/kg that the cert classes it as a simple thermal spring. Sulfate dominates the anion side at roughly 64 mval percent and a faint hydrogen sulfide note rides on the surface. A generous 181.9 mg/kg of metasilicic acid leaves the kind of silica film that makes skin feel noticeably smoother afterwards.
