The public bath area includes the panoramic baths "Mori no Yu" and "Umi no Yu," which overlook the beautiful scenery of Lake Hamana, and the open-air baths "Hoshi no Seseragi" and "Ao no Yawaragi," where you can feel the pleasant breeze. They are filled with the natural hot spring of Kanzanji Onsen, which boasts one of the highest salt concentrations in Japan (with added water, heated, and recirculated). The water warms your body thoroughly and keeps you warm for a long time. With a gender rotation schedule by time of day, you can fully enjoy the changing lake views from each bath, each with its own distinct atmosphere.

A private open-air bath that must be reserved in advance, where you can enjoy a private hot-spring bath. Just as its name suggests, it offers a relaxing space where soft sunlight filters through the trees, allowing you to luxuriate in the famous Kanzanji Onsen all to yourself. The rich salt content in the hot spring gently wraps the skin and provides excellent warmth retention. It is the perfect premium space for spending a special onsen time with family or a loved one, without being disturbed by anyone.
