A Japanese sushi boss has paid a record $3.1m (£2.5m) for a giant tuna at the first new year's auction in Tokyo's new fish market.

Self-styled "Tuna King" Kiyoshi Kimura bought the 278kg (612lbs) bluefin tuna, which is an endangered species.

He spent more than twice the previous record of $1.4m, which he paid in 2013.

Wholesalers and sushi company owners often pay high prices for the best fish at the first pre-dawn auction of the new year.

"I bought a good tuna," Mr Kimura told AFP after the auction.

"The price was higher than originally thought, but I hope our customers will eat this excellent tuna."

Mr Kimura has been the highest bidder at the new year auction for seven of the past eight years.
