Isamu Yokoyama (横山勇, Yokoyama Isamu; 1 March 1889 – 21 April 1952) was a general in the Imperial Japanese Army, commanding Japanese ground forces in China during the Second Sino-Japanese War and Pacific War. In 1948, he was sentenced to death by a military commission for Yokohama War Crimes Trials due to his direct command responsibility for vivisection and other human medical experiments performed at the Kyushu Imperial University on downed Allied airmen. His sentence was later commuted to life imprisonment and he died in prison in 1952.
