The hierarchical structure of feudal Japan was defined by the social system known as the "samurai" class, which included a strict code of loyalty and duty. At the top of the hierarchy stood the emperor, who held a largely ceremonial role. Below him were shoguns, or military leaders, who held real power. The class system further included daimyos (feudal lords), samurai (warrior class), peasants, artisans, and merchants, each with distinct roles and responsibilities. This feudal system influenced governance, land ownership, and societal values, emphasizing loyalty, honor, and martial prowess, which were hallmarks of Japanese culture during this period.
