A unique ion sauna created with inspiration from Korean yellow earth saunas, featuring many white stone clay balls arranged along the walls. The negative ions released from the clay balls are said to promote blood circulation, gently encouraging pleasant sweating deep within the body in mild heat. Self-löyly is also available, letting guests enjoy a luxurious relaxation time surrounded by steam and ions.

An authentic barrel sauna from Finland, standing quietly in the garden's grove. The cylindrical interior, filled with the pleasant scent of wood, is characterized by excellent heat and steam convection. By performing self-löyly, the humidity and perceived temperature inside rise sharply, creating a refreshing sweating experience. Guests can savor a special sauna time that feels united with nature.

A single-person, tsubo-yu-style cold plunge bath located near the sauna room in the public bath. It gently cools down the body after a good sweat in the sauna. After the cold plunge, guests can fully enjoy an exquisite outdoor air bath in the open-air area while feeling the pleasant breeze rustling through the trees in the grove.
