Tokushima Tokushima City
A rich, celebrated onsen fed straight from the source, and a sauna true to its Finnish roots
Tokushima Natural Onsen Aratae-no-Yu is a day-use onsen bathhouse in Tokushima City, Tokushima Prefecture. It takes pride in natural onsen of great purity, fed straight from the source, never recirculated, with no water added at all, and a wide range of baths, among them an open-air bath and a carbonated bath, soothe body and mind. In the sauna area, staff hold authentic löyly sessions with aroma water, and pleasant steam and heat wrap gently around the whole body. A spacious cold plunge and a space for cooling off in the open air, plus a warm-stone room and a restaurant serving authentic soba, mean you can stay comfortably all day.

A bath fed straight from the source, never recirculated (heated, no water added), where you can enjoy the onsen’s rich minerals just as they rise from the ground. The dense water, high in salt and bicarbonate, leaves skin soft and smooth, and it is loved as a bath for beautiful skin. It keeps you warm long after bathing, heating the body through to the core and gently easing everyday fatigue and muscle tension.

A classic far-infrared dry sauna in both the men’s and the women’s main bathhouses (Shiro and Kuro). Thanks to the far-infrared rays given off by the ceramic walls, the heat feels mild and easy to breathe in, yet it warms the body slowly from the core and brings on a heavy sweat. It is a roomy space where you can take your time watching TV.

A refreshing cold plunge right in front of the sauna. It is kept at a crisp, well-judged chill that brings a body heated to the limit in the sauna down in one go. Once you are thoroughly cooled, move to the space for cooling off in the open air in the outdoor area and let the pleasant breeze carry you into the deepest relaxation.
