All rooms offer ocean views × private open-air baths — a modern retreat blending timeless tradition with contemporary comfort, surrounded by breathtaking scenery and the soothing sound of waves.
Reopening on November 1, 2025 as a small luxury Accommodation where every Room offers an ocean view and a private open-air bath with free-flowing hot spring water. Beyond the rising steam lies the horizon of Eastern Izu, where sea and sky melt into one. Listen to the soothing surf, and on moonlit nights a magical “Moon Road” appears across the water. Renowned hot spring water—300 liters per minute—flows from two private sources, gently easing both body and mind. Experience “Japanese cuisine of sea and time,” inspired by Izu’s climate and memories. Crafted by our head chef trained at long-established restaurants, each course is beautifully complemented by Sommelier Excellence–selected wines and local sake for a lingering finish. With only 16 Rooms, we offer complimentary room service—timeless new luxury unique to nostalgic Atagawa.
Having stayed at retreat Hotels all over the whole country, I found this Retreat Onko Chishin to be outstanding in every way.The Room, bath, meals and drinks, and hospitality all delivered a high level of satisfaction, making for a truly pleasant stay.This Hotel has been reborn through the renovation of an existing Hotel, and the quality of the renovation and overall atmosphere were excellent.
We stayed here as a couple. In addition to the in-room open-air bath and the Onsen, we were especially impressed by the ocean view from our Room, and we were able to relax and unwind in a quiet setting. Both dinner and breakfast were delicious, and we also enjoyed meals and drinks via room service; the dining space itself was wonderful as well.The overall atmosphere and interior design throughout the property felt calm and comfortable, making it a stay where we could truly enjoy the luxury of doing nothing. Above all, the hospitality from all staff was exceptional—their service was both attentive and warmly welcoming, which left a lasting impression. The views, the Room, the food, and the staff’s care all exceeded our expectations.Although it was only one night, we had a truly lovely time that became an unforgettable memory. We would definitely like to return, and we highly recommend this Accommodation to anyone looking to spend special time with someone important.

Nostalgic Luxury Atagawa Onsen, where time lingers Nostalgia awakens a new sensibility A distant horizon that feels eternal, and the sound of waves echoing through the mountains, accompany moments of quiet 16 rooms in total: ocean-view rooms with open-air baths and free-flowing natural hot spring water Izu Retreat Atagawa Suiko by OKCS (Onko Chishin)
The Higashi-Izu Atagawa Onsen area boasts the highest number of Onsen towers per unit of land in Japan, creating an atmospheric hot-spring town where steam rises into the air. On full-moon nights, the “Moon Road” reflected on the sea has been selected as one of Japan’s “100 Finest Moons,” captivating travelers for generations. In Atagawa, the charm of a traditional hot-spring town blends with the calm ambience of a seaside village, and its nostalgic appeal still lives on today. We believe that the “richness” found in familiarity and time spent with care are a true form of luxury in modern life. By reexamining Atagawa’s inherent allure through a contemporary lens, we will share it with you thoughtfully.
All rooms offer ocean views and feature private open-air baths. Enjoy a luxurious stay with your own Onsen and scenery, undisturbed by anyone. We also offer four distinctive suites of 100 m² or more. With generous space, you can spend a truly special time. Every room features an ocean-view open-air Onsen bath. And only the suites are equipped with a private sauna. Soak in the bath while gazing out at the sea, and unwind in quiet comfort. A deep sense of relaxation awaits, freeing you from everyday life.
The origin of Atagawa Onsen is said to date back to when rising steam was spotted billowing up from the ground in a field, and the area was named “Atagawa” (“hot river”). Later, in 1931, drilling succeeded in tapping naturally flowing hot spring sources, and during Japan’s postwar period of rapid economic growth it reached its peak amid the group travel boom. As a “Showa-era Onsen town” blessed with abundant hot spring water, it continues to soothe travelers in both body and mind. *Even today, it boasts Japan’s highest number of drilling towers per unit area—13 in total.*
The game corner, tucked away inside the property, is another spot that captures its nostalgic charm. Classic arcade machines and tabletop games line the space, bringing back memories of getting completely absorbed as a child. The moments spent laughing together—cheering wins and lamenting losses—may be a little imperfect, and that’s exactly what makes them so precious. There’s still a sense of “breathing room” here that you can’t find in the digital world.
