TOKYO, July 17 (Reuters) - Japan's top trade negotiator Ryosei Akazawa held talks with U.S. Commerce Secretary Howard Lutnick on U.S. tariffs on Thursday, as Tokyo races to avert a 25% levy that will be imposed unless a deal is clinched by an August 1 deadline.

Prime Minister Shigeru Ishiba said Friday he asked U.S. Treasury Secretary Scott Bessent to advance ongoing tariff negotiations

On July 7, Trump announced 25% tariffs on imports from Japan and South Korea, effective August 1. He also announced separate rates for a number of other countries.
