A New Form of Regional Collaboration. Grand Mercure Ise-Shima Resort & Spa Opens "Bettei Matoya," a Restaurant Featuring Mie Brand "Matoya Oyster," on Wednesday, April 1, 2026.

Grand Mercure Ise-Shima Resort & Spa (Location: Shima City, Mie Prefecture / General Manager: Tatsuya Sakano), an all-inclusive resort hotel situated on a hill overlooking the ria coast within Ise-Shima National Park, opened "Bettei Matoya" on April 1, 2026. This new culinary hub allows guests to experience the nature and food culture of Ise-Shima, centered around Mie Prefecture's proud brand oyster, "Matoya Oyster." The restaurant, which revitalized an existing building on the hotel grounds, will be operated by Sato Oyster Farm (Representative Director: Taiki Hamaji), a company with a 101-year history of oyster farming in Matoya Bay. "Matoya Oyster," cultivated with traditional farming techniques passed down through generations, is an irreplaceable blessing nurtured by the rich waters of Matoya Bay. By expressing the bounty of Matoya Bay and the passion that producers have carefully preserved through their cuisine, delivered in its most delicious state, "Bettei Matoya" offers a unique dining experience specific to Ise-Shima. "Bettei Matoya" was born from the desire for the hotel and producers to collaborate, connecting tourism with local primary industries, and to become a base for promoting the region's charm, rather than just a lodging facility.

Hotel and Producers Collaborate: The Bounty of Matoya Bay and Initiatives for a Sustainable Future

Matoya Bay, located in the Ise-Shima region designated as a national park, is a blessed sea area where three rivers flowing from the mountains carry abundant nutrients, fostering the growth of phytoplankton. It is known nationwide as an unparalleled environment suitable for oyster farming, thanks to the rich nutrients from the mountains and calm ocean currents. Established in 1925, Sato Oyster Farm has built a history of oyster cultivation in the unique natural environment of Matoya Bay in Shima City. The first-generation owner, Tadao Sato, established the revolutionary "hanging oyster farming method," which significantly improved quality, hygiene, and production efficiency. He also introduced the world's first patented technology for sterilizing oysters, the "ultraviolet purification method," establishing a technique to safely provide oysters for raw consumption.

Taiki Hamaji, the fifth-generation owner, has inherited a commitment to technological innovation to adapt to changing social conditions and natural environments while preserving tradition. To reduce the burden on the sea, he intentionally limits production, and oyster shells are recycled as fertilizer for rice cultivation and soil improvers in collaboration with wineries and farmers, demonstrating a strong focus on sustainable practices.

In resonance with these efforts to practice sustainable aquaculture as a Mie Prefecture SDGs Promotion Partner, the hotel is also committed to promoting sustainable tourism, having acquired the international environmental certification program "Green Globe." "Bettei Matoya" also serves as a place to connect the region's nature, food culture, and the producers' passion to the future.

About "Bettei Matoya"'s Commitment

1. The Star Ingredient: "Matoya Oyster"

The symbolic ingredient of "Bettei Matoya" is the brand oyster "Matoya Oyster," cultivated in Matoya Bay, Shima City, Mie Prefecture. Nurtured with care in a rich environment, "Matoya Oyster" is characterized by its lack of bitterness or astringency, and its soft, plump, and lustrous flesh, earning high praise from chefs worldwide. Protected by aquaculture techniques passed down through generations in the region and thorough quality control, this oyster is loved by many as one of Ise-Shima's representative ingredients.

2. "Genshiyaki," an Ancient Japanese Cooking Method

The culinary theme is "Cooked with Fire, Fresh." The main focus is "Genshiyaki," an ancient Japanese cooking method.

Genshiyaki is a traditional cooking method where ingredients are skewered and stood around a charcoal fire, slowly grilling them over indirect heat. By skillfully using both strong and indirect charcoal heat, the umami and aroma of the ingredients are maximized. It's a paradoxical aesthetic that transcends the preconception of "fresh = raw," bringing out the true value of ingredients by cooking them. You can enjoy the inherent deliciousness of the ingredients along with the sounds and aromas of the charcoal fire and the lively atmosphere as they cook.
