Oita, a Gourmet Fresh Seafood Paradise
The fishing grounds of Oita Prefecture are characterized by a diverse environment, including the vast expanse of tidal flats in the Buzen Sea, Beppu Bay surrounded by seawater flowing in from the Pacific Ocean, and the deeply indented rias coastline of the Bungo Channel. The characteristics of these areas are utilized in a wide variety of fisheries in each region, producing fresh fish of high quality.
As a result, a wide variety of delicious seafood dishes are available, such as white fish, which has a light but distinctive flavor of its ingredients, and red fish with elegant fat, both of which can be eaten raw without any peculiar taste.Pay particular attention to fish that are in season, as their flesh is especially firm and their taste is richer. In addition, squeezing Oita's specialty fruit “kabosu” (a citrus fruit) over the fish adds a refreshing citrus flavor that makes the fish even more enjoyable.
Seki-aji” (horse mackerel) and “Seki-Saba” (mackerel) (Oita City), with fans all over Japan
The area off the coast of Saganoseki, located between Oita and Ehime prefectures, is known as “Hayasui no Seto” because of the rapid tidal currents. It is believed that the horse mackerel and mackerel that grow up in this swift current form independent schools that rarely mingle with fish from other areas of the sea. As a result, horse mackerel landed in these waters grow into fat fish with small heads, and mackerel can be eaten raw with little risk of parasites. The horse mackerel and mackerel landed in this area have a moderate fat content and a strong flavor, and are specially treated as “Seki-aji” and “Seki-saba”.
Saganoseki is a rare fishing port in Japan for one-piece fishing, as the undulations of the seabed are complex, making it difficult to fish with nets. The fish are immediately released into a special container to prevent damage and deterioration of flavor due to stress.
In order to maintain freshness, fish are bought and sold using the “Tsuragai” method. Tsuragai is a method in which the price is determined by looking at the fish from the surface of the water, and weight and quality are determined based on appearance alone. This method is used to prevent the fish from getting out of hand and losing its freshness.
Seki-aji is in season in summer, while Seki-saba is in season from autumn to winter. We recommend enjoying them as sashimi or as a seafood bowl. Topping them off with kabosu, a local product of Oita, doubles the umami.
Usuki-fugu" (Usuki City), nicknamed "King"
Usuki-fugu” is popular as a high-class food as well as the tiger puffer from Shimonoseki, Yamaguchi Prefecture. The Bungo Channel and other areas where Usuki-fugu is landed are abundant with organisms that serve as food, and the rapid ocean currents of the Kuroshio Current make the meat tighter and more concentrated in flavor.
Generally, fugu sashimi is made by letting the fish rest overnight or longer to soften the meat before slicing it into sashimi, but “Usuki-fugu” is made by letting the fish rest only a short time after landing, and is sliced thickly and freshly for sashimi. The unique elasticity, flavor, and sweetness of the fish are enough to make food connoisseurs all over Japan swoon.
The natural pufferfish season in Usuki starts on August 20 and can be enjoyed until around April of the following year; from December to March, you can taste the milt with its creamy and rich taste. Sashimi is usually served with ponzu (citrus-flavored soy sauce), but at fugu restaurants specializing in fugu cuisine, you can enjoy a full course meal including A dish made with fugu skin, deep-fried fugu, and a fugu cauldron dish.
Taste a variety of fugu in the prefecture!
Fugu is usually in season in winter, but in Usuki City, you can enjoy fugu in summer as well. It is popularly known as “Natsufugu” (summer blowfish), especially among the locals. Another type of fugu is “Kabosu-fugu” (blowfish), which is raised on “kabosu,” a specialty of Oita Prefecture. This fugu is characterized by its clean, refreshing taste and is a must-try item.

The appearance is like a samurai's sword! “Kunisaki Gin-tachi” (Kunisaki City)
“Kunisaki Gin-tachi” refers to thick-fleshed, silvery-colored hairtail. Nutrients from the rich forests of the Kunisaki Peninsula flow into the sea through rivers, creating an environment rich in a variety of organisms that serve as food for the hairtail. The fish is aptly named “Gin-tachi” (silver sword), and boasts a beauty that shines like silver leaf, like a samurai's sword.
Like Seki-aji and Seki-saba, hairtail are landed one by one using a method called “kogi-tsuri,” in which the fish is caught while rowing the boat, so that the beautiful silver skin can be caught without damaging it. When shipped, the fish is carefully packed in a box to prevent any damage.
The fish is characterized by its light, but moderately fatty, deep flavor. It can be enjoyed in a variety of dishes such as sashimi, deep-fried and grilled fish, tempura, minced pork cutlets, and grilled hairtail coated with sweet and spicy sauce and served over rice. Even those who do not like to eat raw fish can easily enjoy these dishes.
Autumn (from September to October) is especially recommended, when the fish is fatty.
It is characterized by its freshness, grown on a diet of fruit! “Kabosu-hirame” (flounder) (Saiki City, Usuki City, Tsukumi City)
Introducing a fish born from the collaboration of fruit and fish, farmed by mixing Oita's specialty “Kabosu” in its bait. Kabosu is a specialty fruit of Oita Prefecture, with a good balance of sweetness and sourness, and its juice is used as a seasoning. By mixing this kabosu with the bait, the citrus limonene effect removes the fish's distinctive odor and enhances its flavor. In addition, its antioxidant properties work to keep the fish fresher longer.
The first fish we will introduce is “Kabosu-hirame”. It is raised in a one-story flatfish farm commonly known as a “flatfish hut. Here, each flatfish is carefully managed and nurtured, growing to a size of around 1 kg in one year. Before shipping, the fish are fed with a mixture of kabosu juice and fresh kabosu peel. “Kabosu-hirame”, raised with love in this way, can be enjoyed year-round. Tempura and carpaccio are recommended to enjoy its light but rich flavor.
Kabosu-buri” whose fresh flavor enhances the fat of yellowtail (Saiki City, Usuki City, Tsukumi City)
Next, we introduce “Kabosu-buri” (yellowtail with kabosu), whose freshness lasts longer and its flavor is enhanced by the effects of kabosu.
In this area, the sea water temperature does not rise too high in the summer, so the yellowtail is grown all year round with firm flesh. Prior to shipping, yellowtail are fed with a mixture of “kabosu juice” and “kabosu peel powder” to grow into “kabosu-buri”. Especially from November to March, fatty “kabosu-buri” are in season.
During the cold winter months, its flavor can be enjoyed in a wide variety of dishes, such as hot shabu-shabu, fisherman's rice (sashimi served on rice), and buri-daikon (yellowtail radish cooked with seasoned radish). The meat is fatty, yet light and elegant.
Like a Jewel⁉ “Noble scallop” with 120 points in taste and appearance(Oita City, Saiki City)
We will introduce you to the noble scallop, known as an "edible jewel" for its colorful appearance. This shellfish lives in the warm seas of southern Japan.
The colorful orange, red, yellow, and purple shells are all natural, and their beauty is preserved by carefully polishing each shell with barnacles and seaweed attached to the shell. This colorful coloration is due to genetic factors, and one theory is that they evolved to blend in with nearby coral reefs to protect themselves from enemies.
Slightly smaller in size than scallops, the scallops are thicker and more resilient, and have a sweeter and tastier flavor than scallops. The best time to taste them is from late fall to spring, when the water temperature drops.
To directly enjoy the sweetness of noble scallops, sashimi or steamed with sake is recommended. As an arranged dish, it also goes well with pasta and stew.
The Shogun ate⁉ “Shiroshita-karei”(flatfish)
The hometown of Shiroshita-karei is the town of Hiji, surrounded by mountains and Beppu Bay. Near Hinode Castle, which was built around 1600, there is a place where fresh water springs up in the sea of Beppu Bay, and the marbled flounder that grew there was so delicious that it came to be called "Shiroshita-karei," which means "flounder under the castle." During the Edo period (1600-1868), it was also highly valued as a tribute to the Tokugawa Shogunate.
Shiroshita-karei is characterized by its overall rounded shape, wide tail fin, not angular, and small head. In addition, since it lives on the seabed where seawater and fresh water mix, it has no muddy smell and has a mild yet elegant sweetness.
In Japan, flounder is commonly enjoyed as a stew or fried dish, but to bring out the sweetness of Shiroshita-karei, we highly recommend eating it raw as sashimi.
Let's visit the Shiroshita-Karei Festival!
Around mid-May every year, an event is held to enjoy Shiroshita-karei a specialty of Hiji Town, at a special price and in limited quantities. You can enjoy Shiroshita-karei at a reasonable price with sashimi, simmered dishes, and other course meals. Advance reservations are required, so we recommend that you check the duration of the event and make your reservations as soon as possible.
