President Donald Trump disclosed a purchase of between $1 million and $5 million in Kura Sushi USA stock on Feb. 2, an investment that surprised markets and sent Japan-listed Kura Sushi stock up as much as 5.4% — its biggest intraday gain since June 2025, according to Bloomberg.

Kura Sushi USA operates a conveyor belt sushi restaurant chain and trades on the Nasdaq $NDAQ -2.14% under the ticker KRUS. According to the company's annual securities filing, the Japanese parent held a roughly 67% voting stake in its U.S. affiliate as of late October last year. Kura Sushi USA stock jumped more than 6% on the news, according to Restaurant Business.

The purchase was one of more than 3,700 trades recorded under Trump's name in the first quarter of 2026, which also included positions in Nvidia $NVDA +1.30%, Amazon $AMZN +2.19%, and Apple $AAPL 0.00%, according to Bloomberg. Taken together, the disclosed trades carry a cumulative estimated value of between $220 million and $750 million, as Quartz previously reported.

According to Bloomberg, Tsutomu Yamada of Mitsubishi UFJ eSmart Securities pointed to strong results from Kura Sushi's American operations and suggested that the president's stake could be drawing interest from individual investors trading the stock in Tokyo. The investment drew attention in Japan, where social media users speculated about whether Trump had eaten raw fish — a food he has previously said he dislikes, according to SFGate.
