Kenji Doihara, Japanese general (b. 1883)
Kenji Doihara (土肥原 賢二, Doihara Kenji, 8 August 1883 – 23 December 1948) was a Japanese army officer. As a general in the Imperial Japanese Army during World War II, he was instrumental in the Japanese invasion of Manchuria.

As a leading intelligence officer, he played a key role to the Japanese machinations that led to the occupation of large parts of China, the destabilization of the country, and the disintegration of the traditional structure of Chinese society to diminish reaction to the Japanese plans by using highly-unconventional methods. He became the mastermind of the Manchurian drug trade and the real boss and sponsor behind every kind of gang and underworld activity in China.

After the end of World War II, he was prosecuted for war crimes in the International Military Tribunal for the Far East. He was found guilty, sentenced to death, and hanged in December 1948.
