We have introduced self check-in at the facility, and at check-in, we verify your identity by video chat, which is similar to face-to-face verification. Thank you for your understanding and cooperation. When you open the window, you can hear the pleasant sound of the waves and the chirping of wild birds, and you can spend an extraordinary, relaxing time. At night, there is little light around, so you can see the starry sky. Limited to one group, you can enjoy a private time without being disturbed by anyone. The facility is surrounded by nature, so we take measures to prevent insects, but in rare cases, insects may enter the room. We appreciate your understanding. Because it is surrounded by forests, there are many insects, especially in summer. If you don't like insects, we recommend staying in winter when there are fewer insects. We have insect repellent spray and other items available, so please feel free to use them.
