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 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. 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.
The Japanese knew they were behind the Western powers when United States Commodore Matthew C. Perry came to Japan in 1853 in large warships with armaments and technology that far outclassed those of Japan, with the intent to conclude a treaty that would open up Japanese ports to trade. Figures like Shimazu Nariakira concluded that "if we take the initiative, we can dominate; if we do not, we will be dominated", leading Japan to "throw open its doors to foreign technology."
The leaders of the Meiji Restoration (as this revolution came to be known), acted in the name of restoring imperial rule to strengthen Japan against the threat of being colonized, bringing to an end the era known as sakoku (the foreign relations policy, lasting about 250 years, prescribing the death penalty for foreigners entering or Japanese nationals leaving the country). The word "Meiji" means "enlightened rule" and the goal was to combine "modern advances" with traditional "eastern" values. The main leaders of this were Itō Hirobumi, Matsukata Masayoshi, Kido Takayoshi, Itagaki Taisuke, Yamagata Aritomo, Mori Arinori, Ōkubo Toshimichi, and .
