A full-fledged high-temperature dry sauna. In a quiet space with no TV, you can face yourself and work up a sweat all at once. The convective heat powerfully envelops your entire body, delivering a satisfyingly intense heat that seasoned sauna-goers will appreciate. In the silence, as your heart rate rises, you can prepare for an exceptional totonou state.

A thoroughly chilled extra-cold cold plunge bath. It rapidly cools down your body after you've been heated to the limit in a high-temperature sauna. Its crisp coldness tightens the skin and delivers a refreshing sensation that seems to run straight through to your brain. The intense temperature contrast with the sauna is a powerful trigger that leads to deep totonou, truly a cold plunge bath for sauna fans.

A standard-temperature cold plunge bath set at around 19 degrees. This setting is ideal for those who are not fond of extra-cold cold plunge baths or who want to savor the chill at a relaxed pace. The feel on the skin is gentle, allowing your heart rate to settle down gradually. It serves as a comfortable step toward outdoor bathing in the open-air bath, cooling you down while softly enveloping your whole body.
