Classification
Sodium Chloride spring
A sodium chloride spring (formerly classed as a 'pure saline' spring), salty and heat-retaining. At pH 8.7 it is alkaline with a slippery, soft feel on the skin, placing it in Japan's beauty-water family. The wellhead runs at 97.4 °C — among the hottest natural sources in the country, cooled before it reaches the baths. A generous 156 mg/kg of metasilicic acid leaves a thin silica film that makes skin feel noticeably smoother.
