Why Hiroshima oysters are unique
Hiroshima produces around 60% of the oysters in Japan because of its ideal coastal environment. The calm, nutrient-rich waters of Hiroshima Bay allow them to grow quickly and develop a deep, rich taste. “Kaki Komachi,” a variety grown in the prefecture, is particularly large and stores plenty of umami. While November to March is the peak period to enjoy fresh catches, you can also find large Kaki Komachi during the summer months.
Different ways to eat them
In addition to being consumed raw, these shellfish are prepared in several ways. Each cooking method offers a distinctive experience. Here are some of the most popular meals in the region.

Raw oysters (nama-gaki)
Raw oysters, or “Nama-gaki,” offer the best opportunity to enjoy their natural profile. They are usually served shucked on the half-shell with seasonings like vinegar, ponzu, or lemon. Since Hiroshima is also one of Japan’s leading lemon-producing regions, a fresh squeeze of local citrus is the perfect pairing.

Grilled oysters (yaki-gaki)
Grilling enhances the natural sweetness and umami of the meat. Throughout Hiroshima, you can find rustic huts where fresh shells are grilled and served while they are piping hot. For even more depth, adding soy sauce and butter makes Yaki-gaki even tastier.

Fried
When you think of “deep-fried oysters,” a crispy golden exterior likely comes to mind. After biting through that crunchy texture, the soft, juicy center spreads across your palate. They are a local favorite in the prefecture. Oyster tempura is another delicious option, which can be enjoyed with salt or a light dipping soup.

Oyster hot pot (dotenabe)
If you are feeling cold, try an oyster hot pot. This local cuisine is called “dotenabe” in some areas. Raw oysters, tofu, and vegetables are simmered together in a savory miso-based broth. This comforting dish is highly recommended for gatherings and home parties.

Oyster rice (kakimeshi)
This dish is prepared by cooking grains in a flavorful broth and serving them topped with plump oysters. The dish is packed with umami and fresh oceanic notes. Kakimeshi is a staple in local seafood restaurants, but you can also make it at home using a convenient “kakimeshi no moto” seasoning base.
