Question: What made up the three tiers of the japanese political system around 1600?

Disambiguated questions and answers:
context: During the Tokugawa period, the social order, based on inherited position rather than personal merits, was rigid and highly formalized. At the top were the emperor and court nobles ("kuge"), together with the "shōgun" and "daimyō". Below them the population was divided into four classes in a system known as "mibunsei" (身分制): the samurai on top (about 5% of the population) and the peasants (more than 80% of the population) on the second level. Below the peasants were the craftsmen, and even below them, on the fourth level, were the merchants. Only the peasants lived in the rural areas. Samurai, craftsmen and merchants lived in the cities that were built around "daimyō" castles, each restricted to their own quarter. Edo society had an elaborate social structure, in which every family knew its place and level of prestige.

context: Ieyasu's victory over the western "daimyō" at the Battle of Sekigahara (October 21, 1600, or in the Japanese calendar on the 15th day of the ninth month of the fifth year of the Keichō era) gave him control of all Japan. He rapidly abolished numerous enemy "daimyō" houses, reduced others, such as that of the Toyotomi, and redistributed the spoils of war to his family and allies. Ieyasu still failed to achieve complete control of the western "daimyō", but his assumption of the title of "shōgun" helped consolidate the alliance system. After further strengthening his power base, Ieyasu installed his son Hidetada (1579–1632) as "shōgun" and himself as retired "shōgun" in 1605. The Toyotomi were still a significant threat, and Ieyasu devoted the next decade to their eradication. In 1615, the Tokugawa army destroyed the Toyotomi stronghold at Osaka.
