U.S. President Donald Trump has reduced tariffs on Japanese car imports from 27.5 percent to 15 percent, cutting them by nearly half. The deal, reached after months of negotiation, also includes Japan committing $550 billion in U.S. investments and gradually opening its markets to American products, including cars and rice. The 15 percent tariff will apply to almost all Japanese imports, including vehicles and pharmaceuticals, easing uncertainty for major automakers like Toyota, Honda, and Nissan.
