洞川温泉「新泉」
Dorogawa Onsen ShinsenOperated by · 角谷甚四郎
Dorogawa Onsen 'Shinsen' is a simple thermal spring classified as hypotonic, weakly alkaline, and low-temperature. The wellhead temperature is a modest 30.7 °C and total dissolved solids come in light at 0.44 g/kg, so the water is gentle on the body and the mildly alkaline pH gives a soft skin feel. The display board doesn't print colour, taste, or odour notes — those sensory details are best gauged at the bath itself.
