よふど温泉 is a hot spring town in Hyogo, Japan. The water leaves the ground at 25.1°C, cool enough that the baths here are usually reheated. Officially the water is classed as simple spring. Its sources put out around 60 litres a minute.
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.
