Fisheries Day

What Is Fisheries Day?

Every April 13th is "Fisheries Day" (水産デー, Suisan Dē) in Japan. On April 13, 1901, Japan's foundational Fisheries Law (旧漁業法, Kyū Gyogyōhō) was enacted — the legislation that established the modern legal framework for Japanese commercial fishing, including licensing systems, fishing ground rights, and fisheries management. The day was designated in 1933 by the Greater Japan Fisheries Association (大日本水産会) to mark this anniversary and to promote public understanding of Japan's fisheries industry and the importance of sustainable fishing.

Japan as a Fishing Nation

Japan is one of the world's foremost fishing nations — a maritime country whose geography, culture, and cuisine have been shaped profoundly by the sea and its resources. Surrounded by the Pacific Ocean, the Sea of Japan, and the East China Sea, Japan has access to some of the world's richest fishing grounds, where the meeting of warm Kuroshio and cold Oyashio currents creates extraordinary marine productivity. Japanese fisheries harvest a remarkable variety of fish and seafood — tuna, salmon, mackerel, squid, crab, scallops, and hundreds of other species — that are central to Japanese cuisine.

Tsukiji and the Fisheries Trade

Japan's fisheries industry encompasses coastal fishing, offshore fishing, and distant-water fishing fleets that operate globally. The famous Toyosu Market (豊洲市場) in Tokyo — successor to the legendary Tsukiji Fish Market — is the world's largest wholesale seafood market, processing thousands of tons of seafood daily in the predawn hours and supplying the sushi restaurants, supermarkets, and food manufacturers that feed the world's greatest fish-consuming city.

Sustainable Fisheries Challenges

Japan faces significant challenges in sustaining its fisheries heritage. Global fish stocks have declined dramatically from overfishing; Japan's whaling program remains internationally controversial; and the Fukushima nuclear disaster raised concerns about radioactive contamination in Pacific waters. Japan has been working to develop sustainable aquaculture as a complement to wild fisheries, producing oysters, sea bream, yellowtail, and other species in managed farm environments.

Fun Facts

• Tuna auction: Toyosu Market's early morning tuna auctions — where buyers compete for the finest bluefin tuna specimens with elaborate hand-signal bidding — are one of Tokyo's most sought-after visitor experiences, available by advance lottery application.
• Fish consumption: Japan has one of the world's highest per-capita fish consumption rates, averaging approximately 50 kg per person annually — a dietary pattern associated with Japan's exceptional health outcomes and longevity statistics.
