Sajo Seafood, established in 1980, is a seafood processing and distribution company organized into the seafood processing/distribution segment, food segment, distant-water fishery (marine) segment, and others.
The seafood processing/distribution segment handles sashimi-grade tuna processing and distribution as well as general seafood trading, exporting to Japan, Europe, Southeast Asia, and the United States.
The food segment centers on the 'Sajo Haepyo Seaweed' brand, producing laver products and contract processing, with export share expanding rapidly amid overseas health-food trends.
The distant-water fishery segment has improved productivity through better fishing technology, reducing catch volatility and extending fishing days. In 2025 the company established Sajo Fresh Meat as a newly consolidated subsidiary, broadening the portfolio into meat processing.
The company is understood to operate the largest domestic salmon import and primary processing facility, and is pursuing salmon aquaculture technology transfer through overseas joint ventures, reportedly including partners in Norway.
Strengthened global fish stock protection measures create high entry barriers that support incumbent operators including Sajo Seafood.
In laver products, competitors include CJ Seafood, and while Japan has traditionally been the leading export market for sashimi tuna, other regions including North America reportedly overtook Japan in sales recently.
