Only 8 rooms, each with a private open-air bath. Cherish peaceful moments with your loved ones.
A hidden accommodation with open-air baths in every room, nestled in the quiet villa area of Izu Kogen. Each room is equipped with an open-air bath, allowing you to escape the hustle and bustle and enjoy a peaceful time. Meals are carefully prepared by hand, focusing on seasonal ingredients to create each dish with care. The creative kaiseki cuisine changes its charm with the seasons, offering a special moment to savor the blessings of nature through all five senses. Enjoy your private time to the fullest amidst the breath of nature.
I stayed here with a friend this March and was so impressed that I returned in July with my family (as a couple). The dining menu had changed to a summer menu, so we were able to enjoy it again with a fresh perspective. With only eight parties staying at a time, this is a hidden-gem Accommodation: the Rooms are spacious, yet limited to two adults per Room. It’s perfect for anyone who wants to relax and unwind in peace. On the other hand, you won’t find sweeping views of Sagami Bay like those from the balcony of a high-rise Hotel (you can see the sea and Oshima Island, but they feel distant), nor is there an expansive garden. There is also no Shuttle Service from the station, so I recommend it for guests who don’t mind that. It’s well suited for making memories as a couple or with your best friend, and for celebrating anniversaries or special occasions. The in-Room open-air bath is spacious, and after bathing you can relax on chairs on the balcony. The food is delicious and very generous in portion size—and the timing of each course being served is excellent. The bedding was comfortable and I slept soundly. Considering this level of quality and service, the Plan pricing is reasonable. I would definitely like to return again.
トトロうさん 7/8/2026We stayed here for our wedding anniversary.When we arrived by car, the staff came out to greet us, and we were checked in carefully in our Room.The open-air bath in the guest Room was wonderful, and hearing the birds singing was very relaxing.The meals were also delicious, and we were very satisfied.Since it was a special occasion, we made a Reservation for a Plan that included a cake. They also provided wine with the cake, which made my husband very happy.If I could suggest one improvement, it would be great if the refrigerator had a freezer compartment as part of the Facility.We would love to stay again.
