The Keiō Restoration (慶応維新) was a series of events in which Japan was recentralized. It was named after the era in which it began. The central figures were the Tycoon (or shōgun), Tokugawa Yoshinobu, and the Emperor, Kōmon (Kōmei *here*). While the Emperor regained some power, the Tycoon remained quite powerful. Foreign affairs were exclusively the province of the Tycoon, while domestic affairs were shared between the Emperor and the Tycoon. The old administrative structure of the provinces was restored, though several cities were given autonomy.
