The Trump administration secured a $550 billion investment from Japan with 90% of profits going to the US, along with reciprocal tariffs of 15% and expanded market access.

Trump said the U.S. will impose a 15% tariff on Japanese imports under the agreement, which he hailed as "maybe the largest deal in history."

That's down from the 25% levies he proposed earlier this month. Japan's prime minister says duties on autos from his nation will be cut to 15% from 25%.
