Exports to Japan of Vietnamese pangasius (a kind of catfish, local name cá tra) have begun to shift their footing from a quantity contest in frozen fillets to value-added products that have been seasoned or even cooked. According to an industry analysis reported by a Vietnamese economic media outlet on September 3, exports to Japan are about 80% frozen fillets, while processed products in the HS16 classification, such as seasoned and ready-to-eat items, have grown to over 10% of the total, with the shift from volume to quality showing in the figures.
For Japanese agricultural and seafood buyers, this becomes material to consider on both unit price and stable sourcing. In addition to the conventional type of importing fillets and processing them domestically, a sourcing route of finishing semi-processed goods for prepared foods and foodservice on the production-area side before shipping has gained reality. There is room to supply easy-to-handle white fish to the Japanese table, where aging and ready-to-eat needs are spreading.
Against 82% frozen fillets, seasoned and ready-to-eat grew to 11%
In the Vietnam Association of Seafood Exporters and Producers (VASEP) classification, exports to Japan are about 82% frozen fillets, about 7% other fish meat (HS03), and about 11% seasoned and heat-cooked HS16. Whereas worldwide HS16 processed products stay at around 2.4% of total export value, the ratio of processed products for Japan is a notch higher. The 2025 export value to Japan exceeded US$40 million, a level far above 2011's US$2.56 million. Japan counts among the world's markets with strict food-safety requirements, but that very fact has created the ground for highly processed items to enter.
The five years in which pangasius took hold in Japan's seafood market
Imports of frozen fillets to Japan grew about tenfold in five years. With its light white flesh, few bones, and stable price and supply volume, mass retailers have widened their adoption of it as a raw material for white-fish fry and prepared foods since around 2010. For prepared-food and foodservice settings that value raw-material cost and supply stability, pangasius, easy to standardize, is easy to consider as a replacement for white fish.
Precisely because of this foothold, the shift to seasoned and ready-to-eat is being discussed as the next move. The production-area side, having run through fillet volume expansion, is trying to re-secure profitability with higher-unit-price processed products. Ha Tinh Province's tilapia farming for Japan as, moves to secure the production area first and build an integrated chain for Japan are also on the same current.
Exports to Japan seen by HS classification: from fillet-heavy to processed
VASEP expects world pangasius exports in 2026 to be around US$2.3 billion. This is because global white-fish supply is thinning and demand is recovering in multiple markets. However, the ratio of processed products varies greatly by market. Worldwide HS16 processed products were US$48 million in export value as of November 2025, up 13% year on year, but that is only around 2.4% of the total. The level of about 11% for exports to Japan far exceeds this world average. It is a figure that shows the Japanese market leading as a receptacle for processed products.
The average import unit price of processed products is US$5.73-11.3 per kg, higher than fillets. The high unit price means, for the production-area side, room to build up export value without relying on quantity.
Kura Sushi adopted it on its menu at the end of 2025, across over 550 conveyor-belt sushi outlets
At the end of 2025, Kura Sushi, with over 550 outlets nationwide, adopted Vietnamese pangasius on its menu. Adoption by a conveyor-belt sushi chain, a foodservice chain representative of Japan, becomes a sign that uses beyond the frame of household fry raw material are spreading. Exports to Japan were only US$2.56 million and 0.14% of the world in 2011, but expanded 12-fold from 2011 to 2019. Production-area companies are developing items easy to connect to Japanese eating habits, such as kabayaki-style, fish karaage, surimi and kamaboko, and ingredient sets for boxed lunches and izakaya.
Supply conditions Japanese buyers should confirm
What works in sourcing value-added products is traceability from farming to transport, investment in processing technology, the quality-management setup, and conformity with Japan's food-safety standards. Processed products have a higher unit price than fillets, but once you factor in the labor and yield of domestic processing, there are cases where production-area-finished semi-processed goods make sense on total cost. It is worth confirming the production area's lineup and processing equipment at an early stage. VietFish 2026, which steps into business meetings with production-area tours as, becomes an opportunity to see the processing line and hygiene management with your own eyes.
The US tariff headwind redirects white fish to Japan and the CPTPP
It is not only the demand side moving the flow of supply. With the settlement over US anti-dumping duties, part of Vietnamese pangasius is seeking sales channels outside the US. White fish flowing to the CPTPP zone and Japan as US tariffs are finalized this structure means, for Japanese buyers, a phase where options and negotiating room widen. There is room, at a time when volume is easy to secure, to work out trading terms including even high-unit-price processed products.
The practice of using pangasius in care food, prepared foods, and foodservice
Light, with few bones, and because the flesh does not break down easily even after heating, it suits meals for the elderly, hospital catering, and everyday prepared foods. A seasoned HS16 item can be served with just thawing and heating, making it easy to run even in a kitchen short on hands. Kabayaki-style, karaage, and surimi can be placed directly onto dishes already on the Japanese table. Whether to buy fillets and season them in-house or bring in production-area-finished processed products is chosen depending on the slack in processing staff and equipment.
From a competition in volume to a competition in quality: room in supply to Japan
Frozen-fillet volume expansion has run its course, and the next room to grow has shifted to highly processed items. If the production-area side's processing investment and traceability are in place, supply meeting Japan's demand amid ready-to-eat needs and aging will continue. The buyer side too has entered a stage of discerning counterparties not by unit price alone but by processing stage, safety standards, and production-area consistency. Exports to Japan, once all about frozen fillets, have begun to stack up the next layer of seasoned and ready-to-eat.
