What similarities can be drawn between Japan's shotgun system and the feudalism of medieval Europe?

Both Japan's shotgun system and medieval European feudalism relied on a hierarchical structure where land was granted in exchange for loyalty and military service. In Japan, the shogunate held power over the daimyo (feudal lords), similar to how kings granted land to nobles in Europe. Each system emphasized the importance of samurai and knights as warrior classes that upheld the social order and protected their lords' interests. Additionally, both systems fostered a strong sense of loyalty and duty, shaping the cultural and political landscapes of their respective societies.
