Open-air bath located on the top floor
The open-air bath is located outside so you can relax by taking a bath in a natural landscape or in a good atmosphere. You can soak in a hot spring in fresh air in nature and not only relax but also have a moderate fatigue recovery effect. In the open-air bath, the internal organs, blood vessels, and skin are warmed, facilitating the flow of blood and improving the function of breathing and muscles.
