What is the hierarchy in Japan?

The first rank is the emperor, who is nominally the supreme ruler of the country but has no real power.

The second rank is shogun, who is the actual ruler of Japan.

The third level is Daming, equivalent to the vassal of China during the Warring States Period.

In addition, all residents are divided into four categories by strict hierarchy: warriors, farmers, craftsmen and businessmen.

Extended data:

The general is also the largest feudal Lord, directly managing a quarter of the country's land and many important cities. The rest of the region was divided into more than 200 "princes", large and small. The leader of the vassal enjoys the hereditary sovereignty of the vassal, but he must obey the general.

Both the general and Daming have their own retainers, that is, warriors. A samurai gets fiefs and rice from a general or name, but he must be loyal to the general or name. These warriors are generally professional soldiers and have the privilege of sword-wielding, which constitutes the foundation of the Tokugawa era, thus forming a feudal rule system composed of shogunate and vassal, that is, the curtain-vassal system.
