It is the highest ever price fetched. The bluefin tuna was caught off the coast of Ooma, Aomori Prefecture. A nuclear power plant is being constructed in Ooma.
The construction was halted after the Fukushima I Nuclear Power Plant accident, but Yukio Edano, then-Minister of Economy, Trade and Industry, allowed the restart of construction at Ooi in September last year.
The town of Ooma is very famous for its excellent tuna, and part of the opposition to the nuclear power plant there is because of potential danger the exhaust water from the plant may pose to marine life.
Oh well. Aomori Prefecture is solidly an LDP territory, with Higashidori Nuclear Power Plant and Rokkasho Reprocessing Plant already in place. They want more nuclear subsidies. So what the prized tuna fish goes bust?
From Nikkei Shinbun (1/5/2012):
The first auction of the year was held at Tsukiji Market in Tokyo on January 5. Fluefin tuna caught in Ooma, Aomori fetched 700,000 yen [US$8,000] per kilogram, or 155.4 million yen [US$1.78 million] for the whole fish, the highest ever in history. Before this year, 56.49 million yen per fish (210,000 yen per kilo) was the highest. The winning bidder was the same as the last year's winning bidder, sushi shop Kiyomura (Chuo-ku, Tokyo) with "Sushizanmai" sushi chain.
