You can enjoy the rustic atmosphere of a hot spring with the feel of an old-fashioned public bath. The spring quality is acidic, containing sulfur, with a pH of 2.4, and the temperature can reach as high as 45 degrees Celsius, depending on the weather. The hot water is very soft and has a reputation among local customers for being good for neuralgia, rheumatism, and the skin. Also, the hot springs here are drinkable and are good for the body, but don't drink too much. It is best to drink up to 100ml per day.
