A sodium-led chloride spring. Wellhead pH is near neutral at 7.26 but the lab reading of 8.04 places it in the weakly alkaline class. The water is a clear dark-brown with a faint salty taste, moderately mineralized at about 8.4 g/kg dissolved solids. Hypotonic so the soak sits easy on the body, but it carries the heat-retaining, lightly mineral-coated finish characteristic of the old shokuen-sen (salt-spring) tradition.
