The United States plans to impose an additional 15% tariff on goods imported from Japan, according to reports from Kyodo News and the Wall Street Journal that cite White House officials. Kyodo said the surcharge will apply on top of all existing duties, with the administration stressing that Japan "will not be exempt" from the reciprocal tariff framework Washington has recently adopted. The reports did not specify when the measure will take effect or which product lines will be covered. The move, ordered by President Donald Trump, comes after months of signals that a bilateral trade agreement was nearing completion and follows other tariff increases announced this week. Tokyo had not issued an official response at the time of publication, leaving open the possibility of retaliatory steps or renewed negotiations.
