On September 15, 2025, the U.S. Department of Commerce issued a Federal Register notice announcing that new tariff reductions on imports from Japan—including automobiles, auto parts, civil aircraft, and certain other goods—will take effect beginning September 16, 2025. These measures implement the U.S.-Japan trade agreement, which was finalized on July 22, 2025, and formalized by Executive Order 14345 signed on September 4, 2025. Please see our previous post here for more details on the U.S.-Japan deal.
