Relax and savor the slow passage of time while enjoying the stunning ocean scenery and delicious cuisine.

  • It was my first time visiting Shinojima. They offer a Shuttle Service to the port, and the hospitality was very attentive. Above all, dinner was delicious and so plentiful that I couldn’t finish it all—I saved some for breakfast. Thank you. Next time, I’d like to come after adjusting my appetite.If I had one small request, it would be a simple menu list at dinner so I could pace myself better. Of course, enjoying it as a surprise—wondering how much will be served—is also part of the fun. The young foreign female staff member also served us with great effort, which made the stay very pleasant.
