Japan's tariff negotiator Ryosei Akazawa is arranging his seventh visit to the United States for as early as June 26, aiming to end tariffs that are hurting Japan's economy, two Japanese government sources said on Tuesday. The main focus of the visit is expected to be on U.S. tariffs imposed on Japanese automobiles, which have a severe impact on the Japanese economy. Akazawa will also meet with Commerce Secretary Howard Lutnick and others who oversee this area, one of the sources said. The meeting would be the first ministerial-level tariff negotiation since the Japan-U.S. summit held in Canada on June 16. Japanese Prime Minister Shigeru Ishiba and U.S. President Donald Trump agreed to push ahead with trade talks when they met in Canada but failed to achieve a tariff deal. Last month, Japan's trade negotiator said U.S. defence equipment purchases, shipbuilding technology collaboration, a revision of automobile import standards and an increase in agricultural imports could be bargaining chips in tariff talks. In a bid to reach an agreement with the U.S., Japan is also proposing a mechanism to reduce the auto tariff rate based on how much countries contribute to the U.S. auto industry. Japan faces a 24% tariff rate starting in July unless it can negotiate a deal with Washington.
