East Asian countries were never keen and when they see what has happened in Europe I doubt they will change their mind (or they will be extremely careful and picky)
Yes, it seems to me that Japan, and other East Asian (and also South East Asian) countries put a high importance on keeping their ethnic and cultural homogeneity. My experience, as mentioned in other comments, is that they tend to be horrified when they see the consequences of large non-European immigration in Europe, so I doubt that they will adopt similar policies anytime soon.
How does this even work? Is there something in the Japanese Haplogroup that enables this cultural inclusion that no other human can acquire.
If I may address you in a non culturally appropriate manner: Please stop with the bullshit and get real. https://en.wikipedia.org/wiki/Y-DNA_haplogroups_in_populatio...
Urgently!
