In 1868, places dominated by Kumihama or Ikuno magistrate's office in the five provinces of Tango, Tanba, Tajima, Harima and Mimasaka, and the Hatamoto domain in Tajima and Tanba were already consolidated into Kumihama Prefecture, but as separatist movements grew in places dominated by Ikuno magistrate's office, Tajima (except a part of it), Harima, and Mimasaka areas were separated and consolidated into Ikuno Prefecture.
