Core tip: Due to a decrease in the supply of high-quality local bluefin tuna in Japan, during the 30th week of 2025 (July 21 to 27), the auction prices for bluefin tuna at Tokyo's Toyosu Market continued to rise. Among them, the large-sized imported "jumbo tuna" from Canada and the United States performed exceptionally well, with the highest price reaching 14,000 yen per kilogram (pre-tax), driving the high-end auction prices at Toyosu back above 12,000 yen per kilogram after several months.
