An advanced Bonaparm-style auto löyly sauna installed in both Tenkai no Yu and Gankai no Yu. About every 20 minutes, water is automatically poured onto the sauna stones, and pleasantly warm, moderately moist steam gently fills the room. There is no stifling feeling at all, and you can enjoy healthy, deep-from-within sweating while keeping physical strain to a minimum. The scent of wood enhances the quiet, relaxing atmosphere even further.

A compact, one-person pot-style cold bath tucked away in the open-air area. It quickly cools down a body warmed by the sauna’s auto löyly with a sharp chill, delivering a superbly refreshing feeling. After tightening your whole body, you can listen to the sound of the waves from the infinity open-air bath right next door and gaze out over the grand expanse of the Seto Inland Sea while bathing in a superb cool breeze for the ultimate outdoor air bath experience.
