Katsura Tarō
The Japanese Empire had already confirmed the policy of Annexation at the Cabinet Meeting on July 6, 1909. However, it was left only to minimize side effects and obtain an international justification. The Japanese imperial government was preparing a scenario for a "merger petition" to Shigemaru Sugiyama, an advisor of the Iljinhoe. Prior to this, Song Byeong-jun went to the Japanese Empire in February 1909 and held a bargaining for the country. Many times, Itō Hirobumi urged a "merger", but when work was delayed due to the Japanese imperial armed forces plan, he went directly to the Japanese Empire and negotiated a "merger" against the Japanese imperial Prime Minister Katsura Tarō and other members of the Japanese imperial Choya.
