Based on the graphic what effect did Japans location have on cultural diffusion from China?

Japan adopted feudalism from China. The culture of China helped Japan make a civilization by borrowing China's system of government which is a bureaucracy.

They made a checks and balance system to equal power within the branches. the "check" meant that one branch would watch one branch and "balance" them if they were too powerful. if you want more info on this, i would just google checks and balance system.
