Classification
Sodium Bicarbonate-Chloride spring
A sodium-led bicarbonate spring in the classic jūsō-sen style, with a salt-tinged finish from a chloride sub-type. Weakly alkaline and soft on the skin, it sits squarely in Japan's beauty-water family. A generous 120 mg/kg of metasilicic acid leaves a thin silica film that makes the skin feel noticeably smoother afterwards, while a barely-there hydrogen sulfide note hangs over the bath.
