Hoshino Resorts' hot spring ryokan brand, KAI, will open the new KAI Miyajima in Miyajima, Hiroshima Prefecture, in the summer of 2026. This marks a significant milestone for Hoshino Resorts' first foray into Hiroshima Prefecture. The hotel boasts a prime location overlooking the Great Torii Gate of Itsukushima Shrine. All 54 guest rooms feature ocean views, allowing guests to admire the stunning vistas of the Seto Inland Sea and the islands from their window-side sofas. The blue of the Seto Inland Sea is incorporated into the curtains, sofas, and chairs throughout the guest rooms, creating a space that blends seamlessly with the scenery.
The hotel's most distinctive feature is the large public bath on the rooftop. The open-air bath on the south side, facing the sea, immerses guests in the Seto Inland Sea, while the inner bath on the north side, facing the mountain, offers a different kind of bathing experience. Even more unique, Kaimiyajima recreates the Setouchi region's ancient "stone bath" culture. This unique bathing method, dating back to the Kamakura Period and now quite rare, has been reinterpreted in a modern way through research on existing stone baths and historical documents, allowing guests to deeply experience the historical and cultural heritage of the Seto Inland Sea.
Service Features and Brand Characteristics: Inheriting the spirit of hot spring hotels and recreating Setouchi cultural treasures
The "Kai" brand embodies the concept of "authentic yet innovative." As one of Hoshino Resorts' 23 hot spring ryokan (hot spring ryokan) brand facilities in Japan, Kai Miyajima carries the mission of seamlessly blending traditional Japanese hot spring ryokan culture with modern, comfortable accommodations. Hoshino Resorts representative Yoshiharu Hoshino emphasized that the "Kai" brand is a cornerstone of the company, as Hoshino Resorts itself originated as a hot spring ryokan, and therefore holds immense significance for the company.
A key feature of Kaimiyajima's services lies in its deep exploration and preservation of the culture of the Seto Inland Sea region, particularly its revival of the nearly lost "stone bath" experience. Through on-site research of existing stone bath facilities and reference to historical documents, the hotel team has reinterpreted this traditional bathing tradition, dating back to the Kamakura Period, in a contemporary way. Guests can enjoy not only a relaxing onsen experience but also a glimpse into the rich cultural heritage of the Seto Inland Sea, spanning millennia.

All 54 guest rooms at Kai Miyajima are designed with ocean views facing Miyajima Island, offering breathtaking views of the Seto Inland Sea. A key design feature is the custom-designed long sofa by the window, where guests can comfortably admire the stunning scenery of the tranquil Seto Inland Sea interwoven with the distant mountains and islands. The guest room interior design fully reflects the concept of integration with the natural landscape, with the blue hues of the Seto Inland Sea used as the primary color throughout the curtains, sofas, chairs, and other soft furnishings.
While the hotel has not yet announced specific room configurations and amenities, it is expected that as a Hoshino Resorts "Kai" brand facility, each room will be equipped with high-quality amenities and fixtures that meet the brand's standards. The hotel is expected to offer modern accommodations while maintaining the traditional charm of a Japanese hot spring inn, allowing guests to deeply experience the cultural charm of the Seto Inland Sea in a comfortable setting.
Dining Space and Public Facilities: Double Bathing Experience on the Top Floor, Stone Bath Reflects Ancient Wisdom
Located on the hotel's rooftop, Kaimiya Island's large public bath offers two distinct bathing experiences. The south-facing open-air bath offers expansive views of the Seto Inland Sea. Designed to blend seamlessly with the water, the bath creates an open-air experience, as if immersed directly in the water. The north-facing inner bath offers a more private and tranquil setting, overlooking the lush greenery of the mountains.
The inner bath features two specially designed baths with varying temperatures: a "hot bath" that warms the body from the core, and a "warm bath" ideal for extended soaks. Guests can choose the ideal temperature based on their physical condition, achieving complete relaxation. In addition to the modern baths, the hotel will also feature a restaurant and shop, all exclusively for guests, ensuring a private and comfortable stay.
Access and surroundings: Excellent location at Miyajima Exit, 5 minutes to the World Heritage Site
Kai Miyajima enjoys a prime location at Miyajimaguchi-nishi 5-chome in Hatsukaichi City, Hiroshima Prefecture, just a five-minute drive from JR Miyajimaguchi and Hiroden Miyajimaguchi Stations, and approximately a 60-minute drive from Hiroshima Airport. This location offers easy access to Itsukushima Shrine, a World Heritage site, and its renowned Great Torii Gate, while also providing convenient transportation links.
The hotel's surroundings are rich and diverse. Besides taking a ferry to Miyajima Island to visit Itsukushima Shrine, the Miyajimaguchi area itself offers numerous attractions and facilities worth exploring. This area has experienced rapid development in recent years, and Hilton's premium brand, LXR Hotels & Resorts, is slated to open in 2028, demonstrating Miyajimaguchi's growing status as a hub for high-end accommodations, offering a wider range of options for travelers.
