A dry sauna adjacent to the large public bath. Renovated in January 2026 into a stylish and comfortable space, it has been reborn into a higher-quality relaxation environment. In a pleasant room with a gentle aroma of wood, you can enjoy heat that is mild yet deeply warms you from the core. In a quiet space wrapped in soft lighting, you can relax and enjoy blissful sweating and meditation time.

A one-person private cold plunge bath using unprocessed private-source natural cold spring water that gushes up from deep underground, lavishly supplied as free-flowing water. The mellow, gentle spring water softly surrounds the body, letting you enjoy a supreme smoothness and refreshing sensation that tap water can never provide. In your own private space, you can have the fresh spring water all to yourself and experience the ultimate cooldown.
