SETOUCHI RETREAT AONAGI by Onko Chishin
Ehime Prefecture／Dogo Hot SpringAll-suite accommodations where you can surrender to the beauty of the Seto Inland Sea and refined architecture, and savor true tranquility.
[Michelin Guide Hiroshima & Ehime 2018: 5-Star+ Hotel (Red)] [Featured in the Michelin Key selection for three consecutive years, 2024–2026] Architecturally designed by Tadao Ando. Memorable indoor and outdoor spaces include iconic pools and a jacuzzi, “ALL THAT SPA SETOUCHI.” This small luxury Hotel offers just seven all-suite rooms, each equipped with more than ample Facilities. Enjoy a stay where you can take in sweeping views of the magnificent Setouchi scenery through expansive glass windows and fully experience its natural bounty.
We visited for a family trip to celebrate our daughter’s marriage.As it was formerly an art museum, we were overwhelmed by the meticulously designed building by Tadao Ando and the many artworks displayed throughout the property.The Room was extremely comfortable, and the pool we had been looking forward to was wonderful—we were able to fully enjoy this extraordinary space.We expected Western cuisine, but instead were delighted by beautifully refined Japanese dishes. The drink pairings matched to each course were perfect, and every dish moved us.The congratulatory wedding cake we had ordered was also truly delicious and became a wonderful keepsake. We sincerely appreciate the warm hospitality of all the staff.This is a superb Hotel where architecture, art, and food are all in harmony, and we would love to stay again.
baku1027 8/9/2026This Accommodation truly let me fully experience the best of the Setouchi area. I stayed alone, but since the building itself feels like an art museum, time flew by—I wanted to stay much longer. The food was delicious, and the unique mini pairing was just right! All the staff were pleasant and attentive, and the view from the infinity pool was wonderful. Due to my condition I couldn’t soak in hot water, so I was able to relax in my underground Room this time. If you love baths, a Room with a semi-open-air bath would be better. Next time I’d definitely like to choose that Plan. I was also able to make an esthetic Reservation during my stay. The treatment was excellent, and the therapist’s personality was lovely—I enjoyed it very much. Thank you very much for everything!

Introduction of the Accommodation
Naoshima, the main venue of the world-renowned Setouchi Triennale, is home to Tadao Ando’s iconic works such as the Chichu Art Museum and ANDO MUSEUM. Setouchi Retreat Aonagi stands alongside them as one of the signature “Ando architecture” landmarks of the Setouchi region. Originally designed by architect Tadao Ando and partially opened to the public as the “Elleair Museum,” this property has now been reborn—under his supervision—as a small luxury Hotel overlooking the Setouchi Sea. Inspired by “Ao” (blue) for the sea and sky stretching out before you, and “Nagi” (calm) for the serene interior spaces, Tadao Ando has newly shaped this hidden retreat in Setouchi—Setouchi Retreat Aonagi. We invite you to experience it for yourself.
