The army strategist who turned a railway pretext into the conquest of Manchuria
In a 1948 prison diary, he looked back on the Manchurian Incident’s success and wrote that extending the war into China had been a mistake.
Seishirō Itagaki was an Imperial Japanese Army officer and politician who became a central figure in the Manchurian Incident and the expansion of Japan’s war in China. With Kanji Ishiwara, he helped plan the 1931 railway explosion and turned the Kwantung Army’s insubordinate action into the occupation of Manchuria and the creation of Manchukuo. He later served as war minister and commanded forces in several theaters before being convicted of responsibility for aggressive war at the International Military Tribunal for the Far East and executed.
