Ishiwara and Manchuria
Ishiwara was assigned to the Army Staff College as an instructor, followed by a staff position within the Kwantung Army in Manchuria. He arrived there at the end of 1928, some months after the assassination of Zhang Zuolin. Ishiwara quickly realized that the confused political situation in northern China, along with Japan’s already significant economic investments in the area, provided the Kwantung Army with a unique opportunity. He and Colonel Seishiro Itagaki began formulating a plan to take advantage of the situation.
On 18 September 1931, a bomb was secretly planted on the tracks of the Japanese-controlled Southern Manchuria Railway by Kwantung Army elements. Charging that Chinese soldiers had attacked the rail line, Ishiwara ordered Japanese troops to seize the Chinese military barracks in the nearby city of Liutiaokou. He then ordered Kwantung Army units to seize control of all other Manchurian cities without informing the new commander-in-chief of the Kwantung Army, General Shigeru Honjo, or the Imperial Japanese Army General Staff in Tokyo.
The sudden invasion of Manchuria alarmed political leaders in Japan, and brought condemnation down on the country from the international community. Ishiwara thought it most likely that he would be executed or at least dishonorably discharged for his insubordination. However, the success of the operation brought just the opposite. Ishiwara was admired by right-wing younger officers and ultranationalist societies for his daring and initiative. He returned to Japan and was given command of the IJA 4th Infantry Regiment in Sendai.
