  • The Accommodation was very clean, the meals were delicious, and we were able to relax and enjoy the lounge. Breakfast offered such a generous variety that it was hard to choose, and everything was excellent. The staff were also very kind. We would love to stay again. Thank you very much.

  • My mother in her late 60s, I (late 40s), and my 4-year-old son stayed for one night.We arrived at the Accommodation at 1:00 pm. My mother was able to rest in the spacious, traditional lobby with koi, while my son and I changed in the large public bath changing room and headed to the outdoor pool and nearby Iso IKEJIRI. It was close enough to walk even in the heat, we received free tickets at reception, and we enjoyed it to the fullest.My mother checked in at 2:00 pm and made the most of her time—using the lounge and enjoying the large public bath.After returning to the Hotel, my son and I went to the lounge together and had fruit and tea.The view was wonderful—not only from our Room, but also from the lounge.Dinner from 5:30 pm included a sashimi boat platter (the best sashimi I’ve ever had), and even the golden eye snapper was tender—everything was incredibly delicious. On top of that, rice, miso soup, ice cream, alcohol, and more were all refillable. The children’s meal was also excellent—hamburg steak, sashimi, and more—truly a fantastic dinner. Afterward, there was a dessert buffet at the back of the lounge, which we also enjoyed with plenty of variety.On 7/20 there were fireworks launched right in front of the Hotel. We turned off our Room lights and watched together for about 10 minutes in cool comfort—it became a truly unforgettable moment for my son as well. (My mother chose to watch from the lounge instead, and she said it looked wonderful from there too.)The next morning’s buffet was equally satisfying—we sat where we could see the ocean and enjoyed many different dishes.Even after checkout we were able to play at both pool areas as well as Iso IKEJIRI—and we could still use the large public bath changing room. There was an old twin-tub washing machine available so we could wash our swimsuits; we washed them that evening and were able to wear them again on another day.Until now I haven’t often stayed at Accommodations that seem popular with families with children; this time I made a Reservation hoping my child would have fun. In reality both my mother and I were extremely satisfied too—the delicious meals, perfectly relaxing Onsen baths (hot springs), fireworks… everything felt so good it made us question whether this price could be real (the meals alone would have been worth it).Above all else, every staff member provided exceptionally pleasant service. From younger staff to seasoned professionals alike—even small conversations or questions were handled warmly each time. That truly impressed me. Thank you very much—we felt refreshed. We will definitely come again next year as well; I’d love to make this an annual event with my son. Thank you again.
