鈍川温泉 is a hot spring town in Ehime, Japan. The water leaves the ground at 22°C, cool enough that the baths here are usually reheated. Officially the water is classed as simple spring. 5 inns take visitors here.
Mild and low in dissolved minerals. Usually clear and gentle on the skin, which is why these baths are often recommended for first-timers.
Figures from the town's Japanese Wikipedia article.
