What customs keep structure in a society?
Feudalism is the ranks in which Japanese people stand. . The ranks go: shogun at the top, daimyos second, samurai third, and peasants/farmers last. Without this ranking system, it would be disorganized. They all helped each other in their ways. The farmers and peasants provided food for everyone in exchange for protection from the higher ranks. Everyone got what they wanted so they were all happy. The more happy everyone was, the more orderly Japan was and it lasted longer.
Feudal Japan's system of ranks
Bushido is the code of the samurai. Bushido means,"The Way of the Warrior". It is the code that calls the samurai to be honest, fair, and fearless in death. They were also expected to be loyal to their lord to the point where they would die for their lord. This kept structure because people felt more safe that they knew that samurai would protect them based on the code. All samurai had agreed to this so they knew they were all on the page. Because more people felt safe, they stayed, making Japan more popular, and so they kept this society longer.
