What Is “Fresh Tuna”?
The greatest attraction of Katsuura Fishing Port is undoubtedly its fresh, never-frozen tuna. The Japanese term “nama-maguro” refers to tuna that has never been frozen before reaching the customer.
Frozen tuna can sometimes lose some of its moisture and flavor during thawing. Fresh tuna, on the other hand, is carefully temperature-controlled immediately after being landed, allowing visitors to enjoy the fish’s natural flavor, texture, and freshness.
Tuna landed at Katsuura is particularly known for its firm yet pleasantly tender texture and rich umami flavor. The beautiful deep-red color of the lean meat, moist mouthfeel, and subtle sweetness that develops as you chew are among the special qualities of fresh tuna.
Traditional Longline Fishing and Sustainable Practices
Much of the tuna landed at Katsuura Fishing Port is caught using a traditional fishing method known as longline fishing. With this method, a very long main line is fitted with hooks at regular intervals, allowing fishermen to target specific species and carefully catch individual fish.
Longline fishing can help reduce damage to the fish and maintain the high quality of the catch. When properly managed, it can also help avoid indiscriminate harvesting of smaller fish and contribute to the sustainable use of marine resources.
After tuna are caught, fishermen carefully process each fish to preserve its freshness. The tuna are handled individually and stored under carefully controlled, chilled conditions aboard the vessel. This meticulous approach to quality control has helped establish the reputation of Kishu Katsuura fresh tuna as a highly regarded regional specialty.
An Exciting Tuna Auction Experience
At the Katsuura Regional Wholesale Market, tuna auctions begin early in the morning. At around 7:00 a.m., enormous tuna with dark, glossy bodies are lined up throughout the market, creating an impressive sight.
A viewing deck allows visitors to safely observe the auction from above. Watching buyers and market workers move quickly around the market as tuna are inspected and sold is a fascinating way to experience the energy of a working Japanese fishing port.
Because freshness is so important, tuna are quickly transported away after being purchased. Fish can disappear from the market almost as soon as the auction is over, giving visitors a real sense of how fast the seafood distribution process operates.
Guided Market Tours
Guided experiences such as fresh tuna market auction tours and tuna tasting programs have also become popular. These tours provide an opportunity to observe the auction from a closer vantage point and learn about different types of tuna, how professional buyers judge quality, and how the auction process works.
Some experiences also include tastings of freshly landed tuna. Depending on the program and the day’s catch, visitors may be able to compare different varieties such as bluefin tuna, bigeye tuna, and yellowfin tuna, discovering the distinctive flavor and texture of each.
Types of Tuna Landed at Katsuura Fishing Port
Bluefin Tuna
Bluefin tuna, known in Japan as “hon-maguro,” is considered one of the finest and most luxurious types of tuna. It is prized for its rich umami and elegant fat content, with the colder months generally offering especially good quality.
Some large specimens can weigh more than 300 kilograms. Their enormous size makes them particularly impressive when displayed at the market.
Bigeye Tuna
Bigeye tuna gets its name from its remarkably large eyes. It has beautifully colored red meat and a pleasant natural sweetness, making it particularly popular in eastern Japan. It is commonly enjoyed as sashimi or sushi.
Yellowfin Tuna
Yellowfin tuna is named for the yellowish coloration found on parts of its body and fins. It has a lighter, cleaner flavor than fattier tuna varieties and is relatively mild and easy to enjoy.
Yellowfin tuna is especially popular in the Kansai region, where Wakayama is located.
Albacore Tuna
Albacore tuna, known in Japan as “bin-naga maguro,” is named for its unusually long pectoral fins. It is one of the most frequently landed types of tuna at Katsuura Fishing Port.
Although albacore is often used for processed seafood products, the exceptionally fresh fish landed at Katsuura can also be enjoyed as sashimi.
During its peak season, particularly around February and March, the fish develops a richer flavor and pleasantly soft, springy texture.
The Lively Katsuura Tuna Festival
The annual Katsuura Tuna Festival, held in January, attracts visitors from across Japan and is one of the area’s most popular food events.
One of the highlights is a dramatic demonstration in which a whole giant tuna is expertly cut and prepared. The impressive knife work of the skilled fish cutters often draws enthusiastic reactions from the crowd.
The festival also features free servings of tuna soup and sashimi, fresh tuna sales, weight-guessing contests, and a variety of other activities.
For visitors, it is an enjoyable opportunity not only to taste exceptionally fresh tuna but also to experience the lively atmosphere and welcoming spirit of a traditional Japanese fishing town.
Katsuura Fishing Port Nigiwai Market

Live Tuna Cutting Demonstrations
At the event space toward the back of the market, visitors can watch live tuna cutting demonstrations. Skilled professionals use large knives to break down whole tuna in a spectacular display of traditional fish-cutting techniques.
After the demonstration, freshly cut portions of tuna may also be available for purchase, allowing visitors to take home some of the seafood they have just seen prepared.
Enjoying a Meal by the Sea
Food purchased at the market can be enjoyed on a wooden seaside deck. Eating a fresh tuna bowl or sushi while feeling the sea breeze creates a memorable dining experience.
