Final answer:
The rise of feudalism in Japan was influenced by a weak central government, the emergence of samurai as regional warlords, and the establishment of a military ruling class.
Step-by-step explanation:
Three factors that led to the rise of feudalism in Japan were the weak central government, the emergence of samurai as regional warlords, and the establishment of a military ruling class.
During the Heian period, the central government in Japan became weak, leading to a breakdown of public order. In response, provincial families armed themselves and acted as regional warlords, reclaiming land and gaining influence at the imperial court. This allowed them to impose stability and security over rebellion, and the samurai emerged as a major force in Japan's military and political arenas.
Furthermore, the Tokugawa shogunate brought peace and unity to Japan, resulting in a period of prosperity. The daimyos, who were the lords in feudal Japan, took control of their samurai's lands, while the samurai moved to the cities and established a military ruling class. The samurai became the dominant social class, and their control over land and military power solidified feudalism in Japan.
