  • The Room included both a bedroom and a Japanese-style room, and the ocean view was stunning. The panoramic large public bath had the best view of any Accommodation I have stayed at. The free massage chairs after bathing were also very comfortable and helped relax my body. The dinner and breakfast buffet featured carefully selected ingredients with just the right variety of dishes, making it a highly satisfying meal for guests. Thank you very much for your hospitality.

  • We stayed for one night. The staff were friendly and welcoming, and we had a comfortable stay. The food was delicious, even at the buffet. We enjoyed refreshing ocean views from both the Room and the bath. Our grandchild also enjoyed the boat game, table tennis, and manga, and fully enjoyed the Hotel—saying they would like to stay again.
