I'm 100% chinese and I get the red face after the first drink but I can still drink around 8-10 beers before I know I'm done. I've got one japanese friend that can drink anyone under the table (I'm 6ft, 240 and he is 5'4", 140). I once saw him drink 24 beers with no will effect. On the other hand I've got another japanese friend who will be sleeping after just one beer. Go figure.
Cheers,
Aquaman
