Seishirō Itagaki, Japanese general (b. 1885)

General Seishirō Itagaki (板垣 征四郎, Itagaki Seishirō, 21 January 1885 – 23 December 1948) was a Japanese military officer and politician who served as a general in the Imperial Japanese Army during World War II and War Minister from 1938 to 1939.

Itagaki was a main conspirator behind the Mukden Incident and held prestigious chief of staff posts in the Kwantung Army and China Expeditionary Army during the early Second Sino–Japanese War. Itagaki became War Minister but fell from grace after Japanese defeat in the Soviet–Japanese border conflicts, serving as general for several field armies until surrendering Japanese forces in Southeast Asia in 1945. Itagaki was convicted of war crimes by the International Military Tribunal for the Far East and executed in 1948.
