Verified Timeline

Lore & Background

Mutō's path to infamy began on the strategic planning staff of the General Staff Office in 1935. He served as chief of the military intelligence section of the Kwantung Army during the Marco Polo Bridge Incident, an event he is believed to have helped plan, which sparked the Second Sino-Japanese War. Promoted to Vice Chief of Staff of the Japanese Central China Area Army, he led troops during the worst excesses of the Nanjing Massacre. Recalled to Japan in 1939 and promoted to major general that same year, he served on the Military Affairs Bureau of the Ministry of War. Just prior to the Pacific War, he became a lieutenant general and director of the Military Affairs Bureau at the time of the attack on Pearl Harbor.

In Their Own Story

In April 1942, Mutō took command of the Second Imperial Guards Division in Singapore. By June 1944, he commanded Japanese forces on Sumatra in the Japanese-occupied Netherlands East Indies. In October 1944, he transferred to the Philippines as chief of staff for the Fourteenth Area Army under General Tomoyuki Yamashita. There, he was accused of conducting a campaign of slaughter, torture, and atrocities against Filipino civilians, prisoners of war, and internees, while ordering guerrilla containment. Following Japan's surrender, American occupation authorities arrested him. He faced charges before the International Military Tribunal for the Far East, convicted for atrocities in both China and the Philippines, and was executed by hanging at Sugamo Prison on 23 December 1948.
