The Yaeyama Islands government petitioned Okinawa Governor Maruoka Kanji to approve its incorporating Kumeakashima Island (now Taisho Island) and two other islands into its jurisdiction. On January 13, 1890, Maruoka sent a letter requesting permission to allow the Yaeyama Islands to incorporate the islands, as there was a need to regulate fishermen, to Yamagata Aritomo, at that time both home minister and prime minister. (Ref. 1)
On February 7, 1890, Suematsu, director of the Prefectural Bureau at the Home Ministry, responded by requesting Maruoka to report the details of the orders given on December 5, 1885, regarding the postponement of construction of sovereignty markers. (Ref. 2)
On February 26, 1890, Maruoka sent a copy of the documents to Suematsu and asked for a response to his earlier request. (Ref. 3)
