This could be why Honda is building three new assembly plants in the US...
I think Japan initially started building auto plants in the US to fend off the growing pressure for some restrictions as they began to take a larger and larger share of the US auto market. Now, producing where a firm plans to sell makes a lot of sense and it avoids several potential problems. US auto makers have done this in Europe since pre-WWII.
Honda is also building a new plant in Mexico that will employ 3,000.
