The perpetrators consist of six people, Ichiro Shimada, Cho Tsurahide, Otokiku Sugimoto, Takuichi Wakita, Bunichi Sugimura, and Toshiatsu Asai, a Shizoku of Shimane Prefecture. I quit the samurai and became a commoner). Among them, Ichiro Shimada is particularly central. Shimada participated in the First Choshu Expedition and the Boshin War as a footstep of the Kaga feudal clan, and had a career as a military officer even after the Meiji Restoration. After being indignant at Takamori Saigo's Shimono, he was forced to work on national affairs. Hiromasa Sugimura (brother of Bunichi Sugimura) and others have also made a request for military service in the theory of Seikanron. Furthermore, when sending troops to Taiwan, Sugimura and the chief have issued a request for military service again, and Sugimura (Hiroshi), Shimada, and later slashed in the white paper against the rumor that the Taiwanese troops were canceled and the white paper criticizing the treatment of the Saga Rebellion. Riku Yoshinori (Riku Kyusai), who drafts a rumor, is listed. However, these white papers did not produce the expected effects, and Shimada et al. In 1874 (Meiji 7), Shimada and Cho met in Tokyo and had a good relationship. In June 1874 (Meiji 7), the chief entered Sugimura (Kanriku), Riku and Kagoshima to hear the views of Saigo and Kirino Toshiaki regarding the troop dispatch to Taiwan. He has stayed in Kagoshima for about half a year and is studying abroad at a private school. In 1876 (Meiji 9), he entered Kagoshima and warmed up his old relationship with Kirino and others. In October, when the chief returned to the prefecture, the Kamikaze Ren rebellion, the Akizuki rebellion, the Hagi rebellion, and the Shizoku rebellion occurred one after another, and Shimada also struggled to raise troops in Kanazawa, but failed. Furthermore, in the Satsuma Rebellion of 1877 (Meiji 10), Shimada and the chief worked together to raise troops, but while struggling to persuade the surroundings, government troops entered Kumamoto Castle in April. After receiving the information, the plan was canceled, saying that the victory or defeat was decided. After this, Shimada et al. Changed their policy to assassinate high-ranking officials. Sugimoto, Wakita, Sugimura and others also participated in Shimada's plan during this period. Wakita moved to Tokyo in October, Cho in November, Sugimura in December, and Shimada and Sugimoto in April of the following year. Asai, the only Shimane prefecture citizen, was a police officer of the Metropolitan Police Department at the time of the Satsuma Rebellion and served in the Metropolitan Police Department. He was dismissed from work in February (Meiji 11), and in March he learned about Shimada's assassination plan and joined the plan. Their assassination plan went through multiple routes and was heard by Toshiyoshi Kawaji, the top police officer at the time, but Kawaji did not deal with "what can Ishikawa people do?" Takashima Tomonosuke also said the same thing, but as proof of that, "(immediately after the incident) Kawaji flew to the scene, took out a notebook and pointed to a person's name, and it must be the work of these six people. I was spilling tears by hitting my notebook. " In addition, Kawaji was rejected by issuing "Okubo Sangi Incidental Advancement and Retreat" the day after Okubo's funeral.
