みなと湯混合泉(7泉混合)
Minato-yu Blended Spring (7-well mix)Operated by · みなと湯
Mixed source
A sodium-calcium chloride spring — salty and strongly heat-retaining. It is a blend of seven wells gathered in a holding tank, fed by an exceptionally hot source at 89.5 °C, among the hottest natural waters in Japan. Richly mineralized at 16.33 g/kg of dissolved solids, it leaves a mineral film on the skin, while a mildly alkaline pH keeps the feel soft.
