Japanese:
buck teeth, small jaw, small head, short height
If there is a tourism group, you can distinguish Japanese group from Korean or Chinese group based on their face and physique. Japanese group usually contains one or two people really looking like Japanese.
But if there is only one East Asian, you can't distinguish based on their face or physique.
And even distinguishing based on clothes, makeup, and hair styles is not accurate. Because young people usually mimic other countries' culture.
