The Toranomon incident (虎ノ門事件, Toranomon Jiken) was an assassination attempt on Regent Hirohito of Japan on 27 December 1923 by Japanese communist Daisuke Nanba. The incident took place at the Toranomon intersection between the Akasaka Palace and the Diet of Japan in downtown Tokyo, Japan. Crown Prince and Regent Hirohito was on his way to the opening of the 48th Session of the Imperial Diet when the young son of a member of the Diet, Daisuke Nanba, fired a small pistol at his carriage. The bullet shattered a window on the carriage, injuring a chamberlain, but Hirohito was unharmed. Nanba's attempt was motivated partly by his leftist ideology, and also by a strong desire to avenge the death of Shūsui Kōtoku, who had been executed for his alleged role in the High Treason Incident of 1910.
