Chōshū Han in the context of "Government of Meiji Japan"

The Meiji oligarchy was the new ruling class of Meiji period Japan. In Japanese, the Meiji oligarchy is called the domain clique (藩閥, hambatsu).

The members of this class were adherents of kokugaku and believed they were the creators of a new order as grand as that established by Japan's original founders. Two of the major figures of this group were Ōkubo Toshimichi (1832–78), son of a Satsuma retainer, and Satsuma samurai Saigō Takamori (1827–77), who had joined forces with Chōshū, Tosa, and Hizen to overthrow the Tokugawa shogunate. Okubo became minister of finance and Saigō a field marshal; both were imperial councillors. Kido Koin (1833–77), a native of Chōshū, student of Yoshida Shōin, and conspirator with Ōkubo and Saigō, became minister of education and chairman of the Governors' Conference and pushed for constitutional government. Also prominent were Iwakura Tomomi (1825–83), a Kyoto native who had opposed the Tokugawa and was to become the first ambassador to the United States, and Ōkuma Shigenobu (1838–1922), of Hizen, a student of Rangaku, Chinese, and English, who held various ministerial portfolios, eventually becoming prime minister in 1898.
