U.S. tariffs on Japanese goods, including cars and auto parts, are set to be lowered by September 16, according to Japan’s tariff negotiator Ryosei Akazawa in an X post on Tuesday. Akazawa cited a U.S. Federal Register notice dated September 9, which formalized President Donald Trump’s executive order on the bilateral trade deal. The revised tariff rates will take effect within seven days of the document’s publication. Trump’s signing of the order last week resolved lingering uncertainty over the timeline for implementing the reduced 15% tariffs on Japanese autos, following the trade agreement reached between the two nations in July.
