Both Japan and Korea have very specific cultures, and yeah, they screw their work life balance. IIRC Japan is currently working on changing that. But that’s their culture - part of their nation - and flooding it with immigrants erases not only bad parts but also good ones. Hell, look at Germany that struggles with immigrants as far as I know.
Poland, 1,1% according to google, your point?

The only struggles Germany has with immigrants at large is racist government officials using them as scapegoats.
