Self-described Japanese "Tuna King" Kiyoshi Kimura paid a record $3 million for a 612-pound (278-kilogram) bluefin tuna at the first new year's auction in Tokyo on Saturday.
The winning sum for the prized and threatened species at the auction was more than double the previous record from the annual New Year auction, set in 2013.
Kimura, the owner of Kiyomura Corp who also runs the Sushi Zanmai chain, is a regular winner of the annual auctions.
He told Japanese broadcaster NHK that he was surprised by the price this year, but didn’t regret the purchase.
“The quality of the tuna I bought is the best,” he said.
Bluefin tuna normally sells for up to $40 a pound, but the price steeply increases by the year’s end and reaches its highs for prized catches in Northern Japan.
Japan is the biggest consumer of bluefin tuna, leading to the overfishing of the species, with some experts warning that it faces extinction.
“The celebration surrounding the annual Pacific bluefin auction hides how deeply in trouble this species really is,” said Jamie Gibbon, associate manager for global tuna conservation at The Pew Charitable Trusts.

But the Japanese government, together with other countries, is backing plans to rebuild Pacific bluefin stocks of the fish, which is currently depleted by 96 percent from their pre-industrial levels.
