A single bluefin tuna has sold in Japan for 155m yen ($1.7m), almost triple the record price set last year. High bids traditionally mark the year’s first auction at Tsukiji market. Even the buyer, sushi chain owner Kiyoshi Kimura, who also paid out the record price last year said the cost was “a bit high”. This year’s record-breaking fish was caught off north-eastern Japan and weighed in at 222kg.
