AI Pitches Tuna Tech into Global Waters

A Tuna Turn Toward Tech

Japanese ad giant Dentsu is making an unexpected splash in seafood innovation by launching the international rollout of a new tuna-grading AI system. Developed by Yokohama-based startup OPTIM, the technology uses deep learning and image recognition to evaluate the quality of tuna meat from photographs—a process traditionally performed by expert human graders. Japan, one of the world’s premier consumers of tuna, has been testing the system domestically with promising results. By exporting the AI to tuna-rich regions like Southeast Asia and Latin America, Dentsu hopes to bring efficiency and objectivity to global seafood markets.

Fusing Fish and Future

The technology aims to reduce reliance on declining numbers of skilled tuna quality inspectors, while increasing transparency and quality assurance in international seafood trade. Dentsu plans to leverage its global marketing reach to build partnerships with local distributors and fisheries, especially in nations where tuna is a key export. This move aligns with growing trends in food tech and sustainability, offering traceability and standardized quality control. Early feedback from beta tests with Japanese wholesalers signals strong potential for overseas adoption.
