Hidden Hot Spring Inn Tsuki no Akari
Shizuoka Prefecture/AtamiAn adults-only hidden Accommodation with just 15 rooms, where you can feel the sea breeze of Izu on your skin.
With only 15 rooms, this is an exclusive retreat for adults. Situated on a hill overlooking the sea, it offers a creative kaiseki dining experience focused on seafood.
Overall, we were satisfied with the services and had a comfortable stay. However, we were really looking forward to the private open-air bath, but it felt a bit scary for older guests. It was somewhat slippery, and we were concerned that the step into the open-air bath felt unstable.
まやまやまやや 7/20/2026The explanations were very thorough, and it was a pleasure to use.
