There's some interesting history here. Toyota started manufacturing in North America in the 70s-80s largely due to pressure from the US government in the form of tariffs and import restrictions. For example, from https://en.wikipedia.org/wiki/Toyota_Motor_North_America:

"Toyota’s first manufacturing investment in the United States came in 1972 when the company struck a deal with Atlas Fabricators, to produce truck beds in Long Beach, in an effort to avoid the 25% "chicken tax" on imported light trucks." ... "After the successes of the 1970s, and the threats of import restrictions, Toyota started making additional investments in the North American market in the 1980s. In 1981, Japan agreed to voluntary export restraints, which limited the number of vehicles the nation would send to the United States each year, leading Toyota to establish assembly plants in North America."

The book "The Machine That Changed the World", while a bit dated, gives a great overview of the history of Toyota from US automaker perspective.
