An open-view observation sauna located 80 m above ground. Large windows open up panoramic views of Beppu Bay and the city of Oita, creating the sensation of floating as if you were being steamed in the sky itself. The stable heat from the convection stove and the clean interior with a pleasant woody aroma are defining features. As the scenery changes with the passing of time, it becomes a luxurious space where you can take your time and face yourself.

A steam sauna wrapped in a soothing aroma fragrance. Even with its mild temperature setting, the moist steam gently warms your whole body. It is designed to offer a high level of moisture retention, so even those who are not fond of dry saunas can relax comfortably. While being healed by quiet music and fragrance, you can spend a moment in which both body and mind are released.

A crisp, cold cold plunge bath placed right next to the observation sauna. With a stable water temperature of around 17°C, it quickly firms up your body after sauna use. The spotless tub and the clean cut of the water are also excellent. After cooling down efficiently, you are led straight to the rooftop open-air area next door, connecting seamlessly to an exquisite outdoor air-bathing experience as you receive the sky-high breeze all over your body.
