I assume this question identifies actual features, as it is easy to differentiate these countries by language, culture, record and these types of.
Initially, there is the north-south effect, observed additionally in European countries: northerners tend to be bigger and lighter skinned. This will be real within Chinese it self (as anyone who has flown directly from Hong-Kong to Beijing frequently sees), and within Japan (those tragic folks in Tohoku are statistically bigger and whiter-skinned).
