Past year the same buyer paid a then record two million yen (£14,500) for a snow crab at the auction.
A "five shining star" snow crab was auctioned off in Tottori, Japan for a whopping 5 million yen ($46,000) on November 7.
The winter delicacy went home with local crab seller Kanemasa Hamashita Shoten and will be sold to a restaurant located within the high-end shopping district of Ginza in Tokyo. "But it's the custom", Hamashita said in an interview with CNN.
That figure was surpassed Wednesday when the first auction of the season in the town of Shinonsen, Hyogo Prefecture, in western Japan was held.
One thing's for sure: to partake of this particular crab, it'll cost you an arm and a ($4,000) leg.
It's traditionally believed that the first winning bidder of the season at the action will have the best fortune that season.
A spokesman for the successful bidder, who paid five million yen for the 2.6lb crustacean, said: 'I believe it is a good crab filled with meat'.
Hamashita admitted he thought he'd get away with closer to 3 million yen.
Still, "we came to this year's first auction hoping that we would bid the world's highest price again", a representative for his company told Kyodo News.
The catch was made off Tottori Prefecture after the fishing season began in the region after midnight Tuesday.
According to Inamoto, the price exceeded last year's record price of two million yen, which was registered at the time in the Guinness World Records for most expensive crab.
