A panoramic open-air bath adjacent to the panoramic large public bath, offering an outstanding sweeping view of Hagi Bay. The bath is filled with natural Hagi Onsen, said to promote circulation, retain heat well, and help boost immunity. As you relax in the soothing sea breeze, you can enjoy exquisite views that change with the time of day, including boats passing by, the water surface beautifully tinted by the dusk sun, and the brilliance of the morning light, while being deeply refreshed in both body and mind.

A spacious, open-feeling panoramic large public bath with a full view of Hagi Bay through its large windows. The smooth-feeling Hagi Onsen (a chloride spring) helps keep you warm after bathing and is also highly regarded as a skin-beautifying bath. The time spent stretching out your arms and legs and soaking in the natural hot spring while gazing at the wonderful seasonal faces of the sea is truly special. With a wide, clean washing area and complete amenities, it is a space where everyone from overnight guests to day visitors can relax and enjoy the hot spring at their own pace.
