Located on a hilltop at Shirahama Onsen, a luxury Resort Hotel with natural hot spring flow.

Shirahama Onsen Gyoko-no-Yu. An Onsen featuring free-flowing water from a historic natural hot spring source, in an outstanding hilltop location, offering guests inspiration and relaxation. A one-of-a-kind Resort Hotel in Shirahama where you can savor seafood cuisine made with local delicacies.

  • From the Room balcony, we had a panoramic view of Shirahama Beach, the ocean, and the town—an unbeatable location. The Room was spacious and truly relaxing. The Hotel itself was lovely, and having a nice smoking room was a real plus for smokers. In the evening, we enjoyed delicious cocktails at the bar counter, and with live piano music it made for a wonderfully comfortable time. The view from the large public bath was also amazing—you can look down over the sea, and the ocean breeze felt incredibly refreshing. Dinner was an Italian course meal and everything was delicious. The breakfast buffet was great too, with both Japanese and Western options. The Hotel also has a pool and a gym, and it’s close to Shirahama World Safari and golf courses—perfect for families with children as well as golf lovers. It was such a wonderful Hotel that we’ll definitely want to visit again.
