Classification

Sodium Bicarbonate-Chloride spring

A sodium-led bicarbonate spring of the classic jūsō-sen style, with a chloride sub-type adding a salty edge. Weakly alkaline at pH 7.5 at the wellhead, it sits in Japan's beauty-water family, soft on the skin. The water emerges hot at 51.2 °C and carries 1,897 mg/kg of dissolved solids — moderately mineralised with the faint metallic-iron note and salty tang the certificate records at the source.
