CE. In Japan it started about 1100 CE. Feudal Europe and Feudal Japan were two periods of time that were very similar but very different at the same time: politically, socially, and economically.
A major difference between Japan and Europe was their warriors. Warriors were important in both but in Japan they were called Samuri and Europe they are called knights.
Knights in Europe fought in the military in exchange for land. Samuris didn’t own land. They got paid a salary, often in rice. Although they both had a code to follow, in Europe it was called chivalry and focused on loyalty. In Japan it was called Bushido, and focused on maintaining
honor.
