Classification
Sodium-Calcium Chloride-Bicarbonate spring
A hot sodium chloride spring (53.1 °C) with calcium as a secondary cation and a bicarbonate sub-character — the saltiness comes with a bicarbonate softness layered in. Moderately mineralized at roughly 2,214 mg/kg, it carries a notable 199 mg/kg of metasilicic acid, the kind of silica film that leaves skin feeling smoother on the way out. Among Japan's hotter natural sources, with a salty edge and quietly mineral body.
