A Hong Kong sushi chain and a high-end Japanese sushi restaurant jointly won the bid and planned to offer the tuna to customers Wednesday.
The giant tuna, caught off the coast of northern Japan, was among 538 shipped in from around the world for Wednesday's auction.
The record-setting price translates to a whopping 95,000 yen per kilogram, or about $526 per pound.
