The Japanese face is generally longer and wider while the Korean face often has a more prominent jaw and high cheekbones. The Chinese face is typically round in shape. When it comes to the “windows of the soul”, the Japanese eyes are often described as angled upwards, contrary to the Chinese eyes which are usually angled downwards. I have always been able to tell the difference between Chinese, Japanese, Vietnamese, and Filipino from facial features standpoint. Chinese faces are rounder while Japanese faces are square and longer. Vietnamese have a certain characteristic to their noses and the skin tone has slightly darker hue, the same with Filipinos.
