This bath space is proud of its open, spectacular open-air bath, which overlooks the beautiful Shirarahama and offers a perfect sense of unity with the sea and sky. It draws water from "Saginu-yu," the spring of Shirahama Onsen, one of Japan's Three Oldest Hot Springs, and its abundant salt and minerals gently envelop the skin. At night, you can enjoy an extraordinary bathing experience in a magical atmosphere, surrounded by moonlit waves and the quiet sound of the surf.

The closest open-air bath to the sea, where the sound of the waves and the refreshing sea breeze are soothing, along with a refined semi-open-air bath built with stone. Thanks to the rich benefits of the weakly alkaline, hypertonic spring water of "Saginu-yu," a salt film forms on the surface of the body after bathing, helping prevent moisture loss and providing excellent heat-retaining and skin-moisturizing effects. You can gently unwind from the fatigue of your trip while listening to the pleasant sound of the surf up close.

A luxurious private bath where families and couples can fully enjoy Shirahama Onsen's "Saginu-yu" in privacy and without concern. Its weakly alkaline spring quality leaves the skin smooth and supple, and it is known for helping you stay warm after bathing. You can leisurely experience this famous hot spring without worrying about those around you. (Reception at the front desk on the day, first come, first served, fee required)
