On June 14, 1868, Hakodate-fu and Kyoto-fu were established as the first two prefectures under the new changes. At the time, the Imperial government army forces were fighting the Republic of Ezo in the Battle of Hakodate, and despite the proclamation, the city of Hakodate had not fallen yet. By end of June, 11 prefectures had been created, including Edo-fu.
