Japanese Sushi Chain Operator Sets Guinness World Record for Most Expensive Tuna at Auction
Introduction
Kiyomura Corp., the operator of the Sushizanmai sushi chain, has set a new Guinness World Record for the most expensive tuna purchased at auction. The record came after a bid of ¥510.3 million (approximately $4.08 million or $3.2 million, depending on the exchange rate) at the first auction of 2026 at Tokyo's Toyosu fish market.
Main Body
The record-setting bluefin tuna, weighing 243 kilograms, was caught off the coast of Oma in Aomori Prefecture, northeastern Japan. The purchase took place on January 5, 2026, at the Toyosu market's annual New Year auction. The fish was then processed at Sushizanmai's main Tsukiji outlet and distributed to its restaurants across the country. Kiyomura President Kiyoshi Kimura received the Guinness World Records certificate at a ceremony at the chain's main outlet on April 20. He stated that the company intends to continue offering high-quality tuna in future years. This achievement marks the second Guinness World Record for Kiyomura Corp. The company previously held the title for a bluefin tuna bought for ¥155.4 million at the first auction of 2013. According to data from the Tokyo Metropolitan Government, the 2026 winning bid is the highest recorded since comparable records became available in 1999. Furthermore, the trend of top bids at these annual auctions has shown a sharp increase: from ¥36 million in 2023, to ¥114 million in 2024, and ¥270 million in 2025. The practice of making large bids at the year's first auction has become a long-standing tradition among Japanese bidders. Participants see the event as a source of good luck and an opportunity for restaurants to get publicity. In addition, watching the early-morning tuna auctions from the market's observation deck has become a major tourist attraction.
Conclusion
Kiyomura Corp. has secured a second Guinness World Record for the most expensive tuna at auction. This reflects a broader trend of increasing bids at Tokyo's first tuna auction of the year, which serves both as a cultural tradition and a marketing opportunity for the sushi industry.
