  • For a special day

    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.

  • We had a relaxing stay.

    We visited for a short summer getaway.The semi-open-air Onsen suite was wonderful—the room and bath were both spacious. Perhaps because of the higher elevation, it never got too hot on the terrace, and we enjoyed the view while having beer and other drinks.The dishes were beautifully presented and a delight to look at. The fish was delicious, and in particular, every vegetable dish was delicate with great texture—truly impressive.The staff were attentive while keeping a comfortable distance, and we were happy to enjoy many flavors of Ehime through both the cuisine and drink pairings.We also sincerely appreciate that you accommodated our requests regarding the meals as much as possible after discussing them in advance.Thanks to you, our family thoroughly enjoyed our two-night stay. The in-room refrigerator items and snacks also included many products from Ehime, making this a Hotel filled with love for Ehime.

Introduction of the Accommodation

Tadao Ando
A Hotel designed by Tadao Ando, Japan’s world-renowned architect

Naoshima, the central 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 Seto Inland Sea. Inspired by “Ao” (blue) for the sea and sky stretching before you, and “Nagi” (calm) for the serene interior embraced by silence, we invite you to experience our hidden retreat in Setouchi: Setouchi Retreat Aonagi.

Infinity Pool

An iconic 30-meter outdoor pool extending toward the sea The ultimate infinity pool, where the Seto Inland Sea seems to merge beyond the water’s edge. Surrender to the calm sea and sky, and enjoy the gently smiling Setouchi blue. Operating period: Early July to early September (typically)
