A weakly alkaline cold-mineral spring (21.7 C source, pH 8.8) with a faint hydrogen sulfide note at the wellhead. Total dissolved solids sit just below 1 g/kg, so the certificate does not classify it as a therapeutic spring, but the alkaline chemistry still gives the water the soft, slippery hand of the classic Japanese beauty-water family. Because the source is below 25 C the bath is reheated, and it is also diluted, recirculated and chlorine-disinfected before reaching the tub.
