Classification
Sodium Chloride spring
A sodium-dominant chloride spring (Na 84%, Cl 82% of ions) — the classic salty, heat-retaining style of Japanese chloride water. Hot at 52.6 C and weakly alkaline at pH 8.4, it sits firmly in Japan's beauty-water family. Moderately mineralized at about 1,162 mg/kg dissolved solids, with an unusually generous 191 mg/kg of metasilicic acid that leaves a thin silica film and a noticeably smoother skin feel.
