TOKYO - Japan is preparing for possible disruption to exports to the United States after the U.S. Supreme Court struck down President Donald Trump's so-called reciprocal tariffs on Friday, prompting him to announce fresh 10 percent levies.

Tokyo is expected to negotiate with Washington to prevent further tariff increases while committing to investing $550 billion in the United States under a plan previously drawn up in exchange for a reduction in tariffs on Japanese cars and other goods.
