The Nanbu clan sided with the Ōuetsu Reppan Dōmei during the Boshin War of the Meiji Restoration and were punished by the new Meiji government by loss of their northern territories. In November 1869, Kita-gun and neighboring Sannohe District became part of the newly created Tonami Domain (斗南藩, Tonami-han), a 30,000 koku holding created to resettle the dispossessed Matsudaira clan from Aizu-Wakamatsu. In July 1871, with the abolition of the han system, Tonami Domain became Tonami Prefecture, and was merged into the newly created Aomori Prefecture in September 1871.
During the early Meiji period administrative reorganization of Japan on July 22, 1878, Kamikita and Shimokita were divided from former Kita County, and Kamikita was divided into 50 villages. In the cadastral reform of April 1, 1889, the number of villages was reduced through consolidations and mergers to sixteen.
