A dry sauna attached to the open-air bath area on the top floor. The appeal is the rich, pleasant aroma of herbs that surrounds you the moment you open the door. It has spacious seating that also lets you lie down, so you can relax in your preferred posture. The heat is relatively mild, putting less strain on the body, and the soothing herb-filled space gently warms you deeply over time and encourages comfortable sweating.

A single-person circular cold-water bath installed right in front of the herb sauna. The refreshing feeling of quickly rinsing off after the sauna and then stepping into cold water is exceptional. The cold-water bath is set slightly higher in the open-air area, allowing you to cool down while gazing at the magnificent view of Mount Fuji and the sky over Izu Nagaoka. You can experience a luxurious totonou time while looking up at the blue sky, the starry sky, or the moon overhead.
