• I was in Atami for work for the first time in a while, and I wanted to enjoy an Onsen, so after looking around I chose this place. From Atami Station to the nearest station, Imaihama-Kaigan Station, it takes about 1 hour and 30 minutes via the Ito Line and Izukyu Line, and it’s about a 3-minute walk from Imaihama-Kaigan Station to the Ryokan—very convenient. Rather than a typical Ryokan, it truly feels like a hideaway, just as the name Ittoan suggests. The lighting is kept slightly dim, creating a calm atmosphere. Dinner was served in a bright private dining room, and the contrast between light and shadow was wonderful. The staff member in charge—who said they started working here five months ago—explained each dish and kindly chatted with us for a while.There were many dishes, all delicious of course, but what impressed me most was the simmered splendid alfonsino served as a whole fish; it was my first time seeing it like that, and both the presentation and taste were unforgettable. They recommended rice porridge as a late-night meal, but I was far too full this time.I could use a private open-air bath for 50 minutes free of charge; I chose “Akibiyori” and was surprised by how spacious it was and how many trees surrounded it. If you think of the open-air bath area as the first floor, there is an upper level that feels like a reclining bath area on the second floor, so I could enjoy going back and forth between them. It felt more spacious than the large public bath area (ofuro), allowing me to fully relax.Breakfast was also luxurious. Both dinner and breakfast are Japanese-style meals with some Western touches, which I really liked. The Room was spacious, Wi-Fi worked without needing a password, completely stress-free.Everything—absolutely everything—was wonderful here, but above all else، the staff’s courteous yet friendly manner truly reflects what makes this inn special. Unfortunately it was cloudy with rain during my stay، so as I boarded my train home، I promised myself I would return next time under clear blue skies.

  • The free-flowing natural Onsen was amazing. In particular, the “Isaribi” Room with a scenic open-air bath was exceptional—soaking while gazing out at the ocean was truly special. I was also impressed to be served a whole grilled splendid alfonsino. The Room was very clean and comfortable, and my one-night, two-day stay left me feeling refreshed in both body and mind. A wonderful Accommodation I’d love to visit again.
