洞川温泉(新泉)
Dorogawa Onsen (New Spring)Operated by · 洞川温泉ビジターセンター
Sodium Bicarbonate-Chloride spring
A gentle simple thermal spring, weakly alkaline at pH 8.29 — soft on the skin, sitting in the Japanese beauty-water family thanks to its mild alkalinity. Lightly mineralized at 241 mg/kg of dissolved solids, it makes for an undemanding soak. The 29 °C source is a cold-mineral grade spring (under the 'low-temperature' class) reheated before bathing.
