27号、28号、29号、30号の4源泉からの温泉水を混合したタンク
Blended Tank of Wells No.27, No.28, No.29 and No.30Mixed source
Sodium-Calcium Chloride spring
A blended-tank source drawing from four wells (No.27 through No.30), classified as a sodium-calcium chloride spring on the hot side at 58 °C. Chloride accounts for 98 % of the anion balance, making this a remarkably clean chloride water — salty and notably heat-retaining. Total dissolved solids sit at 4.0 g/kg with sodium and calcium close to parity on the cation side, the kind of composition that keeps the body warm long after stepping out.
