Japanese Prime Minister Shigeru Ishiba said the trade agreement Tokyo reached with Washington last month is a “win-win” for both economies but warned that putting the pact into effect will be more difficult than negotiating it. Speaking to reporters in Tokyo on Monday, Ishiba added that subsidy measures tied to the deal will depend on further discussions among political parties, and that he is prepared to meet U.S. President Donald Trump again if needed. Japan’s chief trade negotiator Ryosei Akazawa underscored the hurdles, noting that the accord has not yet been committed to paper—an omission he blamed for delays in tariff reductions. Akazawa accused the United States of trying to rewrite global trade rules and urged Japanese companies not to accept U.S. statements at face value. He nonetheless estimated that a separate $550 billion wave of U.S. investment could ultimately benefit Japanese industry. Ishiba said the government does not plan to alter its defense build-up program and declined to disclose any figures on prospective U.S. defense-equipment purchases. He emphasized that investment decisions will be left to private firms, which, he said, “will not overlook risks before signing contracts.”
