NANJING, CHINA – A Japanese general who led one of the first divisions into the fallen Chinese capital in 1937 was executed by firing squad a decade later, a stark act of postwar justice often omitted from historical accounts. Lieutenant General Hisao Tani, commander of the 6th Division during the Nanjing Massacre, was tried and convicted by a Chinese tribunal in the very city where his troops committed atrocities.
The gates of Nanjing fell on December 13, 1937, initiating a six-week period historians describe as a systematic slaughter. Over 300,000 civilians and disarmed soldiers were killed, with tens of thousands of women subjected to assault. The violence was not a battle but a calculated campaign of terror aimed at breaking Chinese morale.
Tani’s 6th Division was among the initial units to enter the city. Eyewitness accounts from the time, including those from foreign nationals, describe streets littered with corpses and widespread looting. The atrocities were so severe they prompted even John Rabe, a German Nazi party member leading an international safety zone, to appeal directly to Adolf Hitler for intervention.
For nearly a decade, Tani evaded accountability. His reckoning began with Japan’s surrender in 1945. Arrested and extradited to China, he stood trial before the Nanjing War Crimes Tribunal in early 1947. The prosecution built its case on a mountain of evidence, including survivor testimonies, photographs, and diaries.
A foundational legal principle, command responsibility, was central to the case. Prosecutors argued Tani bore direct accountability for crimes committed by his troops, as he had the authority to stop them and failed to do so. The general claimed ignorance, blaming rogue soldiers and exaggerations.

The tribunal rejected his defense unanimously. The scale and six-week duration of the violence rendered claims of ignorance implausible. Tani was found guilty of war crimes on February 6, 1947, and sentenced to death.
On April 26, 1947, the sentence was carried out. As crowds in Nanjing shouted for vengeance, the 64-year-old general was executed by a Chinese firing squad. His death marked a rare instance of direct judicial retribution for the horrors of Nanjing.
The massacre remains a deeply contentious historical chapter. In China, December 13 is a national day of mourning, while in Japan, the event has been periodically minimized or denied by nationalist factions, creating a persistent diplomatic rift.
Tani’s trial established critical legal precedents for holding commanders accountable, influencing international law for generations. His execution stands as a definitive, though singular, judgment on one of the twentieth century’s darkest episodes, a documented verdict for over 300,000 lost lives.
