Enjoy Onsen, restful sleep, and cuisine crafted from carefully selected local ingredients.
Everything was wonderful, and in particular, the service and attentiveness of the female staff member in charge of meals were outstanding. Her hospitality was so exceptional that it felt like a first for me. I would love to visit again to see her. Thank you very much.
たがれれ 10/15/2026Both dinner and breakfast were delicious. We had both meals in the dining area, where private rooms let us relax and enjoy the food at our own pace. Every dish was beautifully presented and tasted wonderful. Even though we kept saying we were full, we finished everything.For an extra charge, we switched to grilled splendid alfonsino at breakfast. The skin was wonderfully crispy, and the fish was delicious. I highly recommend it to fish lovers.The hot spring water was gentle on the skin, and all the staff were kind. We were very satisfied with our stay.We stayed in a detached accommodation and did not see any other guests, so we were surprised at checkout by how many guests were from overseas. Thinking that they had enjoyed a lovely traditional Japanese inn made me happy too.

Introduction of the Accommodation

Ishi no Ya Izunagaoka features a magnificent stone garden spanning 2,000 tsubo. While preserving the best of traditional Japanese Ryokan hospitality, we welcome you with meticulous attention to detail that blends refined Japanese aesthetics with the comfort of a luxury Hotel.

Room
All 22 rooms are detached guest suites with the refined charm of traditional Sukiya-style architecture. Set around a Japanese garden that changes with the seasons, they offer a quiet, relaxing stay. Another highlight is that every room features Onsen. First-floor rooms include a private open-air bath for an especially refreshing soak. Second- and third-floor rooms also offer Onsen in the in-room bath, so you can enjoy its warmth whenever you like.

A mildly alkaline simple Onsen (hypotonic, alkaline, high-temperature) known for its gentle feel on the skin. Its smooth, soothing waters slowly melt away the fatigue of travel. In addition to in-room Onsen baths, we also offer a spacious public bath with an open-air atmosphere. Enjoy the renowned waters of Izu-Nagaoka while taking in sweeping views of Mt. Katsuragi by day and a sky full of stars at night.

Our chef’s special kaiseki course showcases ingredients unique to Izu, including fresh seafood from Suruga Bay and seasonal local vegetables. Savor each carefully crafted dish—beautifully presented, fragrant, and full of flavor—at your leisure.
