To help the economy, a Japanese restaurateur bought a record-setting $736,000 bluefin tuna today at the first auction of the year at Tokyo’s Tsukiji fish market. “Japan has been through a lot the last year due to the disaster,” Kiyoshi Kimura, the restaurateur and now proud owner of the tuna, told the AP….. Bidding crazy prices for bluefin tuna at the year’s first auction isn’t that uncommon in Japan—it’s almost tradition. The Wall Street Journal pointed out that last year’s then-record-setting fish sold for close to $400,000. But this year’s fish is almost double the price and came with this nifty gesture: Kimura’s sushi shop began selling the sushi today for just under $5 per piece—over $90 under its normal asking price.
