In front of Setouchi Beach, diverse rooms, convenient to the art island.

20 minutes by car from JR Kojima Station, this prime location offers a stunning Seto Inland Sea beach right in front. The accommodations range from Japanese, Western, and Japanese-Western style rooms to family rooms, suites, and a Toy Kingdom-themed room. Just a few minutes' drive to the popular "Toy Kingdom" for children, and convenient access to Naoshima, known as an art island. In summer, enjoy swimming at Shibukawa Beach right in front.

  • Due to a late arrival, our stay at the Hotel was relatively short. However, there were activities like a maze and playing on the sandy beach to keep the kids entertained. The buffet was also satisfying with a wide variety of ice cream desserts and even ramen, which is quite unique! We would love to stay again if we have another opportunity! Thank you very much!

  • The dinner buffet was delicious, especially the sea bream shabu-shabu and diced steak. The nigiri sushi was also great, with three different kinds on one plate. I was able to eat dessert too and left completely full. The Onsen had plenty of hot water as well.The sea is close by, so I took a walk along the beach in the morning.
