Hoshino Resorts is set to expand its portfolio of hot spring ryokan (traditional inns) with the opening of KAI Miyajima on July 23, 2026. Located in Miyajimaguchi, the property occupies a vantage point overlooking the Seto Inland Sea and the iconic Itsukushima Shrine. The facility is designed to integrate regional history and craftsmanship into the guest experience, from its architectural use of local stone to its evening cultural performances.
Infinity Hot Springs and Ancient Stone Sauna
The top floor of KAI Miyajima houses an infinity hot spring bath where the water’s surface is designed to appear continuous with the Seto Inland Sea. The bath draws from a private source rich in sodium and chloride ions, noted for its heat retention properties. A distinctive feature of the bathing facility is the Ishiburo, a traditional stone sauna reconstructed based on regional history dating back to the Kamakura period. This ancient-style sauna uses radiant heat at approximately 50 degrees Celsius to provide a gentle steaming effect. Following a session, guests can transition to the Danran-dokoro, a relaxation area offering refreshments including a specialized gelato.
Regional Craftsmanship and Narrative Dance
The ryokan comprises 54 guest rooms designated as Kaimu-no-ma, or “Sea Mist Rooms.” Each room offers views of the surrounding islands and the oyster rafts that characterize the local seascape. The interiors incorporate Hiroshima-based craftsmanship, such as cushions upholstered in Fukuyama denim and lighting fixtures made from Aji glass mixed with stone powder. In the evenings, the property hosts a performance of “Shirabyoshi Dance: The Tale of Itsukushima.” This Gocotchigaku performance involves staff dressed as Heian-period dancers who use song and movement to recount the historical narrative of Itsukushima Shrine.
Culinary Illusions: Aki no Kaiyu Kaiseki
Dining at KAI Miyajima centers on the Aki no Kaiyu kaiseki (multi-course meal), which employs trompe-l’oeil techniques to present regional flavors in unexpected forms. The meal opens with a “Tarte Citron,” a savory seafood mousse quiche presented as a lemon dessert. The center-piece is the Suigun-nabe, a hot pot inspired by the Murakami Suigun pirates, featuring octopus, sea bream, and conger eel. The sequence concludes with a dessert designed to resemble Hiroshima’s famous okonomiyaki (savory pancake), maintaining the theme of visual playfulness throughout the service.
