A compact two-tier dry sauna operated by an Olympia far-infrared gas stove. With no TV and a quiet atmosphere, the room is lit by beautiful yellow glass lighting, creating a comforting Showa-retro space where you can relax and warm up. It is easy to breathe in, and the heat settles gently into your skin, allowing you to quietly and deeply enjoy sweating while imagining the vast nature of Tokachidake beyond the sauna room window.

A cold bath lavishly filled with natural spring water drawn by pipe directly from the mountains of Tokachidake and supplied as water throughout the entire building. Its extremely pure, mellow texture gently and crisply wraps around your heated body after the sauna, bringing a wonderful sense of refreshment. As another cold-bathing experience, it is also popular among connoisseurs to use the acidic spring, known as "the acidic bath," with a source temperature of around 28 degrees, much like a lukewarm bath.
