The Japanese daimyōs begin returning their land holdings to the emperor as part of the Meiji Restoration reforms. (Traditional Japanese Date: June 17, 1869).

The Meiji Restoration (, Meiji Ishin), referred to at the time as the Honorable Restoration (, Goisshin), and also known as the Meiji Renovation, Revolution, Reform, or Renewal, was a political event that restored practical imperial rule to Japan in 1868 under Emperor Meiji. Although there were ruling emperors before the Meiji Restoration, the events restored practical abilities and consolidated the political system under the Emperor of Japan.[2] The goals of the restored government were expressed by the new emperor in the Charter Oath.

The Restoration led to enormous changes in Japan's political and social structure and spanned both the late Edo period (often called the Bakumatsu) and the beginning of the Meiji era, during which time Japan rapidly industrialized and adopted Western ideas and production methods.

Daimyo (大名, daimyō, Japanese pronunciation: [daimʲoː] (listen)) were powerful Japanese magnates, feudal lords who, from the 10th 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 shōgun and nominally to the emperor and the kuge. 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 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.

Daimyo often hired samurai to guard their land, and they paid the samurai in land or food as relatively few could afford to pay samurai in money. The daimyo era ended soon after the Meiji Restoration with the adoption of the prefecture system in 1871.
