On an individual level, people are quite the same. A Swede probably behaves in a similar way to a Japanese. They wake up, work, pay taxes, abide by the rules of society, go out with their friends, and have families. Not much distinction to be drawn there.
But on a civilizational level, there is an enormous amount of disparities. The culture that you experience in Western society is not the one you would experience in Eastern society.
Is Japan very similar to Germany or England? Is China the same as Canada or America? Is South Korea the equivalent of Italy, France or Poland? Is Singapore just a copy of Hungary or Denmark?
And I compare Orientals and Whites because these are two smart races that managed to build great civilizations. Imagine comparing more distinct races like Whites and Blacks or Whites and American Indians.
Race is a biological reality. Never forget that.
