A Rolls-Royce coastal drive & an in-room open-air bath have dramatically evolved into a dual experience: breathtaking ocean views and an ultra skin-beautifying Onsen.

We have also introduced the futuristic “Mirable Bath” human washing machine and the latest showerhead, “Mirable zero,” in every room. 100% natural spring water: pH 9.8 alkaline sulfur Onsen “Pure Beauty Water,” combined with ultra-fine bubble cleansing power—bringing together Natural Onsen × Human Washing Machine in one unforgettable experience.

You may also choose premium A5-grade Japanese Black Wagyu Onsen shabu-shabu. Where extraordinary moments meet heartfelt emotion—with someone special. Enjoy a journey that awakens all five senses.
Stayed on March 6.The Room was spotless and very clean.Having a private open-air Onsen bath in the guest room was the best part.We were satisfied with both the quality and quantity of the meals,and it left a strong impression that the owner visited every table and explained everything so carefully,which showed how much passion they have for this Hotel.There was a power outage that night due to lightning, but the staff responded quickly and flawlessly.After power was restored, we were also glad to be able to see the laser message display.Finally, we even got to experience a seaside drive in a Rolls-Royce convertible, making it an extremely satisfying trip.We will definitely return.
Yahoo!トラベルユー... 3/13/2026We stayed for one night to celebrate our 10th wedding anniversary.It felt like a Resort Hotel with a private beach.The Room was clean and stylish.The guest Room with an open-air bath fed directly from the source was innovative, with a remote-controlled cover.The Onsen left my skin smooth and silky, as if old skin and dead cells had been gently removed.The laser show was also spectacular, and seeing someone being proposed to was truly moving.Dinner was more than enough, and we were completely full.The A5-grade Wagyu beef was of course delicious, but my favorite dish was the ajillo.It was incredibly good when we lightly toasted the baguette over charcoal and soaked it generously in the ajillo.It was about a 30-minute drive from Shirarahama Beach and the Toretore Market area, but that made it pleasantly quiet, which we actually appreciated.We’d love to visit again.

Introduction of the Accommodation
A “miraculous ocean panorama” unfolding day and night—an experience only possible on a secluded coastline.
As far as the eye can see: the ocean, the horizon, and drifting clouds. At night, enjoy a sky full of stars and shooting stars—sometimes you can even see the stars at eye level! Have you ever experienced how bright the night can be by natural light? On moonlit nights, a dazzling “moon road” appears across the sea. In the silence, all you’ll hear is the sound of the waves. Please enjoy it together with our finest Onsen in your Room’s open-air bath!
