The Tokugawa shogunate hands back power to the Emperor of Japan, starting the Meiji Restoration.

The Tokugawa shogunate, also known as the Edo shogunate, was the military government of Japan during the Edo period from 1603 to 1868.

The emperor of Japan is the hereditary monarch and head of state of Japan. The emperor is defined by the Constitution of Japan as the symbol of the Japanese state and the unity of the Japanese people, his position deriving from "the will of the people with whom resides sovereign power". The Imperial Household Law governs the line of imperial succession. Pursuant to his constitutional role as a national symbol, and in accordance with rulings by the Supreme Court of Japan, the emperor is personally immune from prosecution. By virtue of his position as the head of the Imperial House, the emperor is also recognized as the head of the Shinto religion, which holds him to be the direct descendant of the sun goddess Amaterasu. According to tradition, the office of emperor was created in the 7th century BC, but the first historically verifiable emperors appear around the 5th or 6th centuries AD.

The Meiji Restoration , referred to at the time as the Honorable Restoration , and also known as the Meiji Renovation, Revolution, Regeneration, Reform, or Renewal, was a political event that restored imperial rule to Japan in 1868 under Emperor Meiji. Although there were ruling emperors before the Meiji Restoration, the events restored practical power to, and consolidated the political system under, the Emperor of Japan. The Restoration led to enormous changes in Japan's political and social structure and spanned both the late Edo period and the beginning of the Meiji era, during which time Japan rapidly industrialised and adopted Western ideas, production methods and technology.
