A high-temperature dry sauna that delivers intense heat well above 100°C. In the men's bath, the synergy of a large far-infrared heater and an auto löyly machine creates powerful waves of heat that envelop the whole body. In the women's bath, the fragrance drifting from the aroma pot above the heater enhances relaxation, allowing for high-quality sweating along with a different scent each day.

A cold plunge bath softened further after being drawn from a well and then softened, making it one of Tokyo's smoothest and most mellow bathing waters. Though the temperature is a crisp, refreshing 15°C or so, the fine bubbles from the bubble function gently stimulate the skin and create a revitalizing cooling experience, as if the protective layer on your skin were being lifted away. Its defining feature is the moist, silky feel unique to soft water.
