A semi-open-air bath that blends into the spectacular scenery of Lake Toya, plus a full-fledged self-löyly sauna
"Toya Sun Palace Resort & Spa" is a large lake resort hotel in Sobetsu, Usu District, Hokkaido. Its spacious public bath features a rare semi-open-air structure with fully retractable openings, offering sweeping panoramic views of Lake Toya. In the standing open-air bath, where you can feel as if you are one with the lake, you can enjoy the gentle waters of the sodium chloride and sulfate spring, known for its excellent heat-retaining properties. A variety of baths, including jacuzzis and reclining baths, are available, along with a full-fledged sauna that supports self-löyly. You can even gaze out over the lake from the sauna room windows, and after working up a pleasant sweat, enjoy a blissful cool-down on the terrace by the lakeshore while feeling the breeze.

The spacious public bath has a semi-open-air structure with fully retractable openings. It is filled to the brim with gentle sodium chloride and sulfate spring water, known for its excellent heat-retaining properties. A variety of baths, including jacuzzis, cypress jet baths, reclining baths, and floating baths, are available, so you can enjoy a leisurely soak to suit your preference.

A spectacular open-air bath with Nakanoshima, the symbol of Lake Toya, right in front of you. Resting against the edge of the standing bath gives you a curious sense of immersion, as if you were soaking in the lake itself. At night, it becomes a premium viewing spot for the long-running fireworks festival, letting you take in the vividly colored, magnificent fireworks while soaking in the bath—a truly luxurious experience.

This dry sauna, attached to the public bath area, supports self-löyly. Pour water over the sauna stones and enjoy the rising steam and comforting heat that envelop your whole body. In front of the spectacular view of Lake Toya through the window, work up a deep sweat, then cool your heated body in the refreshing cold plunge bath.
