You can enjoy black water derived from ancient rainwater

A small pool and ice sauna
The current chairman visits public baths nationwide, and from his observations, many offerings are available only in our facility. There is no doubt that once you enter our small, frozen sauna where your hair freezes (the room is kept at -10 ° C), you will be addicted. Bath salts are added daily to the nearby jacuzzi. There are many scents that are popular with women, such as lavender and rose.
