Industry minister Hiroshige Seko paid a visit to a Subaru plant in the United States to make the point that Japanese firms help the US economy.
Seko visited the plant on Thursday in the mid-western state of Indiana. It produces nearly 350,000 cars a year. That's about half of the units Subaru sells in the US.
The visit came as US President Donald Trump considers a plan to raise tariffs on auto imports.
Seko said, "This plant is creating jobs in the local community. Such investment by Japanese firms is a significant boost to local economies and Japan's government is encouraging more in the US."
Half of the cars Subaru sells in the US are imported from Japan.
If Trump implements the higher tariffs it will deal a serious blow to the company's business.
