Kiyomura Corp., which operates the sushi chain Sushizanmai, bought the tuna at an auction at Tokyo’s Toyosu fish market in January.
The tuna was cut at Sushizanmai’s main Tsukiji outlet and served at its restaurants across Japan.
It marks the second Guinness World Record title for the operator, which was recognized for the bluefin tuna it bought for 155.4 million yen ($980,000) in the first auction of 2013.
The year’s first auction has become a tradition among Japanese bidders, who see it as a source of good luck and a chance for restaurants to capitalize on the publicity.
