In the UK we’ve had Japanese, US, Euro and home grown production for many years.
There was some concern about rights of association - ie the right to join a union - when the Japanese opened up factories but they had no problems at all, they just had a single site union agreement - so you work at one place and you join the one union there, you can carry pre-existing membership of other union with you but it is just will not be recognised at the negotiations although it could represent you in company proceedings - but there is hardly any point, might as well join the on site union.
What we noticed as a massive cultural change was the removal of status on staff facilities - so in UK and US companies you’d have different levels of toilets, and canteen facilities, but in Japanese ones everyone has access to all the facilities - there is only one canteen, and everyone uses it. This really reinforces the idea that all of the workers are there for a specific collective purpose - high quality production.
Another aspect of Japanese factories is that absolutely everyone has worked on the production lines, including the directors, occasionally senior managers will return to work on the production lines every now and then if only for a couple of shifts.
My guess is the US experience of Japanese production culture is similar to the UK experience. It is very noticeable that using local UK workers produces equal quality (and sometimes even higher) that the parent factories in Japan.
My conclusion is that the only difference from UK/UK companies and Japanese ones is the management - the workforce is exactly the same and Japanese companies emphasise the need for harmony rather than competitiveness - where each departement is a contributor and not a stand alone part.
Sure I doubt that all in Japanese factory production is sweetness and light, but their management techniques with the same workforce produces a quantifiably better result.
