Classification

Sodium Chloride spring

A simple thermal spring pumped at Shimizu in Ibaraki City, neutral at pH 7.2 and lightly mineralized at 793.6 mg/kg of dissolved solids, so it bathes gently with little bite. It carries a fair amount of metasilicic acid (69.9 mg/kg), the kind of silica that leaves a thin film for noticeably smoother skin, and runs colorless, transparent and odorless.
