TOKYO, April 7 (Reuters) - Japanese Prime Minister

Shigeru Ishiba said on Monday he told U.S. President Donald

Trump in a telephone call that his tariff policies are extremely

disappointing and urged him to rethink.

"I've told the President that Japan has been the biggest

investor in the United States for five straight years and the

tariff policies could hurt our Japanese companies' investment

capabilities," Ishiba told reporters after the call with Trump.

Ishiba also said he agreed with Trump to continue

constructive dialogue on the issue.

Trump's decision to impose a 25% levy on auto imports, and a

reciprocal 24% tariff on other Japanese goods, is expected to

deal a huge blow to Japan's export-heavy economy with analysts

predicting the higher duties could knock up to 0.8% off economic

growth.
