Japan’s transport ministry said on Monday that it has introduced a new certification system to make it easier to import passenger cars manufactured in the United States.
The initiative was agreed upon with the United States in July 2025, following concerns raised by U.S. President Donald Trump over the relatively low number of American vehicles sold in Japan.
Under the revised rules, U.S.-built cars that already meet American safety and environmental standards no longer need to undergo additional tests for exhaust emissions and noise in Japan.
The ministry also updated related ministerial ordinances on Monday to implement the changes and streamline the certification process for exporters.
Toyota Motor Corporation said it plans to import three U.S.-made models, including the Camry sedan, while Honda and Nissan are considering similar moves.
Japanese Trade Minister Ryosei Akazawa tested a U.S.-built Toyota Highlander SUV on Monday as part of the government’s demonstration of the simplified import system.
The Ministry of Economy, Trade and Industry said it is leasing two U.S.-made vehicles to evaluate the “reverse-imported” models under local road conditions.
Officials said the new system is intended to increase the number of American cars in Japan, promote trade cooperation, and reduce administrative hurdles for exporters.
