What was one way that Japanese and European feudalism were similar?

Japanese and European feudalism was similar in different aspects:

- An economy based on land, the presence of a centralized state structure but which is relegated to the background by the division of power, and the clear distinction of a warrior group.

- Private armed groups and with it a militarization of society. Another would be the lack of pressure from external groups (the viking and muslim incursions and invasions for the case of europe and the mongols for japan that took place centuries later, but without success) making possible the particular social gestation of both places in the dawn of feudalism.

- The rise of both feudal worlds, emerged from a previously regular centralized political system that in the case of france was the old carolingian empire and for japan the imperial decline of the heian period.

Feudal Japanese and European societies were built on a system of hereditary classes. The nobles were at the top, followed by warriors, with tenant farmers or serfs below.
