On March 5, 1896, the Japanese government announced Imperial Edict 13. This was implemented on April 1 under Home Ministry Ordinance 2. Okinawa, excluding the wards of Naha and Shuri, was divided into the five administrative districts (gun) of Shimajiri, Nakagami, Kunigami, Miyako, and Yaeyama, and each district came within the jurisdiction of a local administrative office. Regarding incorporation of the Senkaku Islands into Japanese territory, it is presumed that the Senkakus entered under Yaeyama jurisdiction with this Imperial edict, as the Yaeyama Islands government had petitioned for jurisdiction. (Ref.1)
