Pacific bluefin tuna is a highly prized fish in Japan, where skilled chefs transform it into delicious sashimi, sushi, and nigiri. The annual auctions at Tokyo’s Toyosu Market draw bids from restaurants looking for the best and biggest fish. The first auction of the year is always the most anticipated, with the winning bid often reaching exorbitant amounts.
In 2025, a Pacific bluefin tuna weighing 608 pounds was sold for $1.3 million at the market’s first auction. This hefty price tag was the second-highest recorded since the market began keeping track in 1999. The winning bid was placed by the Onodera Group, a Michelin-starred Japanese sushi restaurant chain, in partnership with tuna wholesaler Yamayuki. The company plans to serve the fish at 13 of its restaurant locations.
The massive fish was caught by a 73-year-old fisherman named Masahiro Takeuchi near the town of Oma in northern Japan’s Aomori prefecture. Takeuchi described the fish as “as fat as a cow” and expressed his happiness at catching such a prized specimen.
Sushi chefs prefer tuna from Oma due to its fatty diet and cold habitat, which give the fish the perfect taste and texture for sashimi. Pacific bluefin tuna, known as “black diamonds,” are large migratory fish found throughout the Pacific Ocean. They are warm-blooded, allowing them to retain body heat even in frigid waters, making them fast and powerful swimmers.
Pacific bluefin tuna were overfished for decades due to their rich flavor, but conservation efforts and fishing limits have helped the species rebound. U.S. commercial fishers have been gradually allowed to harvest more Pacific bluefin tuna in recent years, contributing to their economic and ecological recovery.
The sale of the massive Pacific bluefin tuna at the Toyosu Market’s auction highlights the continued demand for this prized fish and the importance of sustainable fishing practices to ensure its long-term survival.
