Koyasan Onsen, served at Fukuchi-in, is a lightly mineralized simple thermal spring — 171 mg/kg of dissolved solids, weakly alkaline, soft on the skin. The wellhead emerges at only 28.7 °C, so the bathwater is reheated, recirculated through filtration, and chlorinated for sanitary reasons before reaching the tubs.
