Kiyoshi Kimura, who owns the Sushizanmai chain, paid 333.6 million yen (£2.5 million) for the 278-kg (613-lb) fish caught off the coast of northern Japan’s Aomori prefecture, or double what he had paid six years ago, reports Telegraph UK.
“The tuna looks so tasty and very fresh, but I think I did too much,” Kimura told reporters outside the market later.
“I expected it would be between 30 million and 50 million yen, or 60 million yen at the highest, but it ended up five times more.”Loading...
Kimura had held the record for top price paid for a single fish at the new year’s auction for six straight years until 2017. But last year, the owner of a different fish restaurant chain paid the highest price.
After the auction, the fish was taken to one of Sushizanmai’s branches located in the old market of Tsukiji.
Tuna is prized around the world for its use in sushi, but experts warn growing demand has made it an endangered species.
