A significant majority of Japanese firms have found the business impact of U.S. President Donald Trump's tariffs within expectations and have not found it necessary to change investment plans, a Reuters survey showed on Thursday.

Japan’s exports fell for the first time in eight months as the US tariff campaign weighed on global trade, raising the risk of a technical recession after the economy contracted at the start of the year.

Prime Minister Shigeru Ishiba, speaking after the G7 summit in Canada, confirmed that negotiations with Washington had failed to yield a full tariff agreement.
