Kenji Doihara
The Tientsin incident of 1931 was the operation planned by the Kwantung Army of the Empire of Japan to place Puyi on the throne of the Japanese-controlled Manchuria. The plan, orchestrated by Colonel Kenji Doihara and Colonel Itagaki Seishiro was successful, and Puyi became the Chief Executive of Manchukuo the following year. Puyi was subsequently enthroned as the Kangde Emperor in 1934.
