Tamana Onsen, with 1300 years of history, is a famous hot spring long beloved as a beauty hot spring. It is a colorless, clear, mildly alkaline simple hot spring with a slightly silky feel. Four types of baths are offered as free-flowing natural spring baths: a full natural cypress bath made from Kiso hinoki, a natural spring bath in granite, a pot bath made of Shigaraki ware, and a rock bath made of iron plate stone, each offering its own atmosphere and water feel. It is said to help smooth and refine the skin and to be effective for rheumatism, neuralgia, muscle pain, joint pain, and sensitivity to cold. In the open-air baths, you can relax and enjoy a soak while looking at a 60 m waterfall.
