The Meiji period, also known as the Meiji era, is a Japanese era which extended from October 23, 1868, to July 30, 1912. This period represents the first half of the Empire of Japan, during which Japanese society moved from being an isolated feudal society to a Westernised form. Fundamental changes affected its social structure, internal politics, economy, military and foreign relations. The period corresponded to the reign of Emperor Meiji and was succeeded upon the accession of Emperor Taishō by the Taishō period. On February 3, 1867, the 14-year-old Prince Mutsuhito succeeded his father, Emperor Kōmei, to the Chrysanthemum Throne as the 122nd emperor. On November 9, 1867, then-shōgun Tokugawa Yoshinobu tendered his resignation to the Emperor, and formally stepped down ten days later. Imperial restoration occurred the next year on January 3, 1868, with the formation of the new government. The fall of Edo in the summer of 1868 marked the end of the Tokugawa shogunate, and a new era, Meiji, was proclaimed.
