Tomoyuki Yamashita
The Manila massacre was one of several major war crimes committed by the Imperial Japanese Army, as judged by the postwar military tribunal. The Japanese commanding general, Tomoyuki Yamashita, and his chief of staff Akira Mutō, were held responsible for the massacre and other war crimes in a trial which started in October 1945. Yamashita was executed on 23 February 1946 and Mutō on 23 December 1948.
