I know that guys from Japan, China or Korea don’t easily get thick facial hair (as in: having a literal beard) or it’ll take longer to grow in comparison to Euro-Western men for some reason even if both groups didn’t shave, what I mean is in a week: the American guy is starting to grow a beard while the Japanese guy hasn’t gotten it yet despite both waiting 7 days unshaven.
Like this: both guys work for the same corporation where suits are required & must be presented with decorum, the Japanese guy hasn’t shaven for that long but still looks clean while the American guy shaved yesterday before work as the beard has grown, so basically the American guy has to shave frequently while the Japanese guy doesn’t use the razor that much.
It’s the same thing with SE Asian (Thai, Vietnamese, Filipino, Indonesians) guys since it’s not common for them to heave beards within a week on the same extent as European & Western men. Rather it only displays a small patch of facial hair instead of a full beard if left unshaven, it grows at a slower pace for them while its rapid for both Western & European guys.
I grew up in the US and I always used “Asia” on its own to mean East Asia and think everyone else I knew did as well. Anywhere else just was called something else (India, the Middle East, South-East Asia, and so on). I don’t think it hit me until I moved to Japan in my 30s, but I definitely see it a lot still in USAmerican-heavy online groups.
