Kushimoto-cho OnsenCalcium-Sodium Chloride spring
A calcium- and sodium-led sodium chloride spring — salty and heat-retaining, leaving a faint mineral film on the skin. Richly mineralized at 9,132 mg/kg of dissolved solids, it is isotonic and neutral in pH, so it sits gently against the body. The bath water is diluted, reheated, recirculated, and chlorine-disinfected before reaching the pool, and the certificate marks it as bathing-only, not for drinking.
