President Donald Trump is threatening to impose higher tariffs on Japanese exports to the United States over what he claims is the country’s unwillingness to buy American-grown rice.

President Donald Trump expressed frustration with U.S.-Japan trade negotiations on Monday as Treasury Secretary Scott Bessent warned that countries could be notified of sharply higher tariffs as a July 9 deadline approaches despite good-faith negotiations.

Business sentiment among large Japanese manufacturers has improved slightly, according to a survey by Japan’s central bank released Tuesday, although worries persist over President Donald Trump’s tariffs.
