At Itō Onsen, "Itō Ryokuyu" offers one of the rare garden open-air bath-equipped rooms.
We stayed in the Kozu Room.The Room was spacious and comfortable.Although the facilities are mostly shared with Kowakien, they are clearly separated in various ways, which was great. The meals were delicious and more than we could finish. All the staff were courteous, and we had a wonderful time.This is an Accommodation I can recommend.
shimatamama 8/3/2026It was an Accommodation where we could feel thoughtful, understated care. They read the atmosphere and created a mood that lifted our spirits—it reminded me of service that exceeded expectations, like what I experienced at Four Seasons Hotel Chinzanso Tokyo during an off-site meeting more than 20 years ago.It was a very windy day, but the open-air bath in our Room was completely sheltered from the wind. We enjoyed a long, relaxing soak while being soothed by birdsong, including Japanese bush warblers and black kites.The Room, relocated from a traditional old house, was spotless and let us feel the passage of time within the building. My mother in her 80s felt nostalgic, while my daughter in her 20s seemed to enjoy the extraordinary experience.Thank you for your warm hospitality.Thank you very much.
