I still think they look like white people at times.
They(Japanese) say that it'd be boring to have characters that look all the same(black hair, slanted eyes etc.) so they do that to differentiate. Here's a couple of comments from some Japanese natives from some blog with my quick translation
"If all the characters were Asian, it'd be boring because everyone looks the same."
"Actually it feels like Disney kind of made things more of a mess don't ya think?"

"anime grandma.
This is why. After WW2 and America occupying Japan, this is how anime has been seen as for a long time. US military cartoons are what anime has basically tried to look like and it's predecessors(anime) has amounted to this basically."
If some Japanese folks can say this, Idk why people defend the designs and say it's all japanese looking. I'm aware of how outside characters are depicted (Long nose, blond hair, blue eyes, shaky japanese in the original dub.) but that's an exception.
Having characters like Super Saiyan Goku, u know turning blue eyed and blonde haired sort of evokes that thought and feeling of characters teetering on the edge of being caucasian.
Like this for example:
These characters are tweaked to look western.
also not every character is some animes are Japanese but going by your original point, you'd say that they look japanese. One piece characters aren't even Japanese as per the mastermind:
The guy behind the series said this himself.
So, that's my point. Sometimes they look white.
