Daimyo Title
Powerful Japanese magnates who ruled most of Japan from their vast hereditary land holdings.
Daimyo or daimio (大名, daimyō) were powerful Japanese magnates, feudal lords who, from the 15th century to the early Meiji period in the middle 19th century, ruled most of Japan from their vast hereditary land holdings. They were subordinate to the shogun and nominally to the emperor and the kuge (an aristocratic class). In the term, dai (大) means 'large', and myō stands for myōden (名田), meaning 'private land'. From the shugo of the Muromachi period through the Sengoku period to the daimyo of the Edo period, the rank had a long and varied history. The backgrounds of daimyo also varied considerably; while some daimyo clans, notably the Mōri, Shimazu and Hosokawa, were cadet branches of the Imperial family or were descended from the kuge, other daimyo were promoted from the ranks of the samurai, notably during the Edo period.
Lore & Background
The shugo daimyō (守護大名) were the first group of men to hold the title daimyō. They arose from among the shugo during the Muromachi period (approximately 1336–1573). The shugo-daimyo held not only military and police powers, but also economic power within a province. Major shugo-daimyō came from the Shiba, Hatakeyama, and Hosokawa clans, as well as the tozama clans of Yamana, Ōuchi, Takeda and Akamatsu. The greatest ruled multiple provinces. The Ashikaga shogunate required the shugo-daimyō to reside in Kyoto, so they appointed relatives or retainers, called shugodai, to represent them in their home provinces. The Ōnin War was a major uprising in which shugo-daimyō fought each other. At the end of the fifteenth century, those shugo-daimyō who succeeded remained in power. Those who had failed to exert control over their deputies fell from power and were replaced by a new class, the sengoku-daimyō, who arose from the ranks of the shugodai and jizamurai.
Reader's Guide
The Battle of Sekigahara in 1600 marked the beginning of the Edo period. Shōgun Tokugawa Ieyasu reorganized roughly 200 daimyo and their territories into han, which were assessed by rice production. Those heading han assessed at 10,000 koku (50,000 bushels) or more were considered daimyo. Ieyasu also categorized the daimyo according to their relation to the ruling Tokugawa family: the shinpan were related to the Tokugawa; the fudai had been vassals of the Tokugawa or allies in battle; and the tozama had not allied with the Tokugawa before the Battle of Sekigahara. Daimyo were required to maintain residences in Edo as well as their fiefs, and to move periodically between Edo and their fiefs, typically spending alternate years in each place, in a practice called sankin-kōtai. In 1869, the year after the Meiji Restoration, the daimyo, together with the kuge, formed a new aristocracy, the kazoku. In 1871, the han were abolished, and prefectures were established. Around 200 daimyo returned their titles to the emperor, who consolidated their han into 75 prefectures.
