Simple

Classification

Sodium-Calcium Chloride spring

An alkaline simple thermal spring rising from the 'Ichinotaki No. 2' source at Katsuura Onsen in Wakayama. At pH 8.7 it is distinctly alkaline, giving the slippery, soft-on-the-skin feel of Japan's beauty-water family. The water is colorless and transparent with no taste, though a faint hydrogen sulfide note is detectable at the wellhead. Lightly mineralized at 455 mg/kg of dissolved solids, it is gentle on the body, and the inn serves it as untreated free-flow with no dilution, heating, recirculation, or disinfection.
