Germany had, just 10 to 15 years prior, shown pretty thoroughly that they were competing with the best of them in terms of "self-determination of a single nation bound together largely, but not exclusively, by ethnicity, shared language, and implied lineage to predecessor states".

Japan today and Germany 196x share the labour shortage. But Japan's demographic problem adds a second incentive to encourage immigration, whereas Germany back then was experiencing the baby boom. So, if anything, Japan has an even better case for immigration today than Germany 60 years ago.
