The “greatest deal” between the U.S. and Japan: transforming the bilateral alliance and reshaping Japan’s traditional political model

On July 23, 2025, President Donald Trump announced the conclusion of a “great” tariff agreement between the United States and Japan. Under the deal, Washington agreed to reduce tariff pressure on Japanese goods from 25% to 15%. These new rules also apply to automobiles, Japan’s key export item, with the U.S. agreeing to eliminate quantitative restrictions.

In return, Japan pledged to expand market access for certain American goods, including increasing rice imports within a duty-free quota and removing technical barriers for U.S. automobiles.

Additionally, Japan committed to launching a new investment initiative worth up to $550 billion through state banks and agencies (Japan Investment America Initiative).
