Near Senjojiki, a traditional Japanese-style Onsen resort situated on a cape overlooking the Atlantic Ocean.

Nanki Shirahama is one of Kansai's premier resort destinations, known for its sea and Onsen. A new traditional Japanese-style Hotel, "Hamachidori no Yu Kaishu," has opened near the famous Senjojiki, perched on a cape overlooking the Pacific Ocean.

  • Because our Room had an open-air bath, we were glad we could enjoy the Onsen even with our 1-year-old daughter who is not yet out of diapers. Since it was an ocean-side Room, the view was amazing. While my husband and I took turns watching our daughter, I was also able to use the large public bath, which was very relaxing.The Room was very spacious and had a low bed as well as floor futons. The refrigerator was stocked with complimentary water and plum juice for each guest; I especially appreciated the plum juice—it was refreshing and delicious.In the first-floor lounge, coffee is available 24 hours a day, and there are also food services depending on the time of day. Dinner is served in two seatings, so different food is offered for each group—such thoughtful hospitality.At dinner, they prepared a private room with a child’s chair, and our daughter even received a luxurious kids’ set meal. Each time an adult dish was served, various staff members kindly spoke to her—“You’re doing great eating! Good job!”—which made us very happy. Of course, every adult dish was outstanding as well, and we were especially excited about the large sashimi boat platter! (We won’t post photos so it can be a surprise for future guests.) Since you can adjust what’s included in the service based on how much you eat personally, we were completely satisfied with both quantity and quality. If there’s one thing to watch out for, it’s simply not overeating. Haha.The souvenir shop on the first floor is open late at night too, so it was convenient to casually stop by to pick up extra drinks or souvenirs.We were truly happy to spend our daughter’s first trip to Wakayama comfortably at this Accommodation. Thank you very much for your wonderful care and hospitality.

  • We stayed at Kaishu in Shirahama for my mother’s birthday trip. We had previously visited Kaishu in Ishikawa and loved it, so we were sure this one would be great as well—and it was exactly as expected, with a wonderful atmosphere, attentive service, and excellent meals. My mother was very happy. We were able to relax in the Onsen and spend a truly meaningful time together.
