Yes most East Asians look very similar. They're culture is one that promotes being a gear in the machine, to shun any form of self expression. Their genetics also don't vary much in terms of appearance, just the same black eyes black hair x 10000000000.Put this all together and you have a people who all kind of look the same. White people also look similar when you have groups that dress & act the same, just look at those mindless people who take their appearance from whatever is in style.
