A hierarchical social structure: Both systems were based on a hierarchy of social classes, with the emperor or king at the top, followed by nobles, knights, and peasants.
Land tenure: In both systems, land was granted by the ruler to nobles in exchange for military service or other forms of loyalty.
Military obligations: Nobles in both systems were required to provide military service to the ruler in times of war.
Economic relationships: In both, peasants worked the land and paid rent to the nobles, who owed military allegiance and economic tribute to higher noble or monarch.
However, there were also some key differences between feudalism in western Europe and feudalism in Japan:
The role of religion: In western Europe, the Christian church played a major role in feudal society, providing spiritual guidance and legitimacy to the social hierarchy. In Japan, Buddhism and Shintoism played similar roles, but the religious institutions were less powerful and less centralised.
The power of the central government: In western Europe, the central government was often weak, and power was decentralised to local lords. In Japan, the central government was much stronger, and the emperor had more direct control over the country.
