益子温泉 is a hot spring town in Tochigi, Japan. The water leaves the ground at 28.4°C, cool enough that the baths here are usually reheated. Officially the water is classed as simple spring. Its sources put out around 200 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.
