I agree that these videos should be made by people in those countries.
I never lived in Japan, but I've been there about a dozen times for business trips, which is why I think my Shinjuku video was so accurate and well-recieved by people who actually live there.
Unfortunately almost all urbanist YouTubers are Americans, and there are various socioeconomic and cultural explanations for that.
I link to international content often but sadly there's not a lot of it out there
