Cultural differences were an explicit problem when Toyota started to bring their manufacturing to America. This itself does not take any stand on work ethic, etc. Just that the Toyota system was a well designed totality that depended on the japanese culture as a necessary primer to get everything else working.
Culture differences are a real thing, and human processes are non-trivial to transport directly for this reason. Training is of course the solution, but this needs to be explicitly taken into account - not just presume that everyone will behave automatically the same if they are given job titles and a factory floor where to operate.
The Japanese manufacture most of their American market cars in America, using American labor.
Take your biases somewhere else, this isn't the place for them.
