Answer: Feudalism as a form of the political and economic system.
Step-by-step explanation:
Even if they were geographically separated and had no contact, Japan and Europe had an almost identical government system during the Middle Ages. The feudal system was developed in both Europe and Japan. At the head of that politically valuable system was the ruler as the owner of the land (and if the state or monarch gave him land to use) there were warriors under him, and the last "link in the chain" was the peasant, the one who cultivated the land. These elements characterize both Japan and Europe. What has also been the case in Europe and Japan is inheritance. The serf remained a serf, and his children came to this position, while the feudal lord left the land to his descendants.
