What Kaneko Sangyo does

Kaneko Sangyo Co., Ltd. (金子産業株式会社) is a Saga Prefecture-based seafood company and consolidated subsidiary of Nissui Group (Nippon Suisan Kaisha) operating five integrated business lines from Karatsu, Japan. Its aquaculture division runs 13 bluefin tuna farms across five prefectures under the Nissui Maguro brand, supported by an in-house extruded pellet (EP) feed line that verticalizes input supply. The food products division processes and distributes finished seafood, the cold storage division operates 15,000 tons of capacity with 150 tons/day of freezing throughput, an aquaculture feed division supplies external fish farmers, and a petroleum division operates an ISO 14001-certified fuel business. The company employs 251-500 people.

The business model is B2B across multiple segments: it sells branded and processed tuna into Japanese retail and food-service channels, rents cold storage capacity, supplies feed to regional aquaculture operators in Kyushu, and distributes petroleum products. Revenue is generated via unit sales of aquaculture output, processing margins, storage/logistics fees, and fuel markups, with the Nissui Group network providing the primary route-to-market for seafood lines.

Technically, the company leverages its proprietary LLC (Long Life Chill) cold-preservation process, ammonia/CO2 natural refrigerant freezing systems, and a full traceability system linking farm-level data to finished products. It was the first Japanese operator to obtain Marine Eco-Label Japan (MEL) Chain of Custody certification for bluefin tuna and holds ISO 22000 and ISO 14001 certifications; in 2024 it added on-site solar generation producing approximately 74,000 kWh annually to underpin its environmental commitments.
