> Can someone explain why they think this is a detrimental practice for native Japanese?
You're quoting a practice applied to foreigners, but you say "for native Japanese". Maybe there was a typo, or I could be misreading?
Presumably they’re asking why this is being done, since it’s obviously not for the benefit of the immigrants.
