Cause

During the final stages of World War II, American forces moved to retake the Philippine capital from Japanese occupation. Japanese naval forces under Admiral Sanji Iwabuchi, ordered to defend Manila, chose to resist rather than withdraw, setting the conditions for intense urban combat and the targeting of the civilian population.

Event

Between 3 February and 3 March 1945, Japanese troops under Admiral Iwabuchi carried out widespread atrocities against Filipino civilians in the city of Manila as part of the Battle of Manila. At least 100,000 civilians perished from all causes during the battle, including killings directly attributed to Japanese forces, constituting one of the gravest war crimes committed by the Imperial Japanese Navy.

Consequence

Admiral Iwabuchi died by suicide before the battle ended. General Tomoyuki Yamashita and chief of staff Akira Mutō were tried for command responsibility over the massacre and other war crimes beginning in October 1945. Yamashita was hanged on 23 February 1946 and Mutō on 23 December 1948, establishing significant precedent for holding commanders accountable for subordinates' atrocities.
