Atami Eki Zen Onsen Yokujō

A sodium-and-calcium chloride spring with sulfate adding quiet body, this is a moderately mineralized, neutral-pH water with noticeable substance — chloride at 2,917 mg/kg and sulfate at 1,216 mg/kg. The wellhead is among Japan's hottest natural sources at over 74 °C, and it is served as untreated source flow (no dilution, heating, recirculation, or disinfection), reaching the bath at around 41 °C. The salt-and-sulfate balance makes for a heat-retaining soak that lingers on the skin.
