In 1885, with the establishment of the cabinet system, the Home Ministry was reorganized by Yamagata Aritomo, who became the first Home Minister. Bureaus were created with responsibilities for general administration, local administration, police, public works, public health, postal administration, topographic surveys, religious institutions and the national census. The administration of Hokkaidō and Karafuto Prefectures also fell under the direct jurisdiction of the Home Ministry, and all prefectural governors (who were appointed by the central government) came under the jurisdiction of the Home Ministry. In 1890, the Railroad Ministry and in 1892, the Communications Ministry were created, removing the postal administration functions from the Home Ministry.
