According to numerous media reports, a single bluefin tuna sold for 32.49 million yen (nearly $400,000 US) at Tsukiji market in Tokyo, the highest price paid for a single fish since records began.
The fish's growing popularity across Asia has raised fears it will soon be fished into commercial extinction and several headlines referred to the fish as "endangered", although the species is currently not classified as such by scientists.
"It was an exceptionally large fish," said a Tsukiji spokesman, Yutaka Hasegawa. "But we were all surprised by the price."
The fish was reported to weight 342 kg (roughly 750 pounds).
