As Japanese man, I could say....
Man gets more money than woman in general.
Woman is relatively bad driver.
Woman is more emotional than man. Man, in stead, is more logical than woman.
Woman does not have map in their head, so they are easy to be lost.
In old and traditional work place, woman is difficult to promote since man thinks they are going to leave company after they get married.
Elderly people are more worry if woman does not get married after 30 years old than man.
Compared with western countries, we are still developing country in terms of this. But recently we are changing day to day basis, so please kindly to Japanese old man. lol
