Sajo Industries is a core affiliate of the Sajo Group, engaged in deep-sea fishing (tuna, pollock, squid), meat processing, canned tuna manufacturing, soy sauce production, cold-storage warehouse operations, and real estate leasing.
According to JobKorea corporate data, the Q1 2026 revenue mix was roughly 23% seafood processing, 22% canned seafood, 17% tuna and cod products, 11% livestock slaughter and meat, and 27% other.
Its flagship consumer brands include canned tuna and the Haepyo cooking oil brand acquired in 2004, and the company holds the No.2 position in the domestic tuna can market behind Dongwon F&B.
Within the group's pyramid ownership structure, Sajo Industries sits beneath the unlisted holding company Sajo Systems and serves as the parent of major affiliates such as Sajo Seafood, Sajo Daerim, and Sajo Oyang, forming the upstream link in the group's catch-to-processing-to-distribution chain.
Raw material sourcing centers on deep-sea catches of tuna and pollock along with imported grains and oils, directly exposing earnings to international commodity prices and currency swings. The group has recently strengthened vertical integration by acquiring food distributor Foodist and starch producer Sajo CPK.
Competition overlaps with Dongwon Industries and Dongwon F&B in tuna and canned goods, and with CJ CheilJedang and Ottogi in cooking oil, with pricing power for cost pass-through often tied to industry-wide simultaneous price hikes.
Ancillary businesses such as cold-storage warehousing and real estate leasing also contribute to overall results.
