"Tokushima Natural Hot Spring Aratae no Yu" is a day-use hot spring facility in Tokushima City, Tokushima Prefecture.

In the sauna area, it provides an authentic löyly service using aromatic water, where pleasant steam and heat gently envelop the entire body. It also features a spacious cold plunge bath, outdoor air-bath areas, as well as a bedrock bath and a dining area where you can enjoy authentic soba, allowing you to stay comfortably all day long.

A free-flowing source bath where you can enjoy the luxurious spring ingredients just as they emerge from the ground, with heating but no added water. The rich water, packed with salt and bicarbonate, is known for its moisturizing and skin-smoothing effects and is cherished as a beauty bath. It is less likely to leave you chilled after bathing, and it warms you thoroughly from deep within, gently easing daily fatigue and muscle tension.

A classic dry sauna equipped in the men’s and women’s main baths (White and Black). Thanks to the far-infrared effect emitted by the ceramic walls, it feels mild and easy to breathe in, while gently warming you from deep within and encouraging abundant sweating. A spacious room where you can relax while watching TV.

A refreshing cold plunge bath located right in front of the sauna. It is kept at a crisp, pleasantly cool temperature, allowing you to quickly cool down after heating your body to the limit in the sauna. After cooling off thoroughly, move to the outdoor air-bath area in the open-air section and enjoy the ultimate relaxation in the pleasant breeze.
