A simple thermal spring in Yuasa-cho, Wakayama. With pH 9.5 it sits at the strongly-alkaline edge of the scale; sodium dominates the cation side (94 percent of equivalents), giving the slippery, soft-water feel associated with Japans beauty-water family. Source temperature is 30.4 C — a cold-side low-temp spring that is reheated for bathing. Mineralization is light (194 mg/kg dissolved solids), so the water is mild rather than assertive.
