Prince Yasuhiko Asaka: Japanese Imperial Commander of Nanjing Massacre Who Escaped Justice
from World History: True Stories of the 20th Century · host World History
Prince Yasuhiko Asaka, a member of Japan’s imperial family and commander during the Nanjing Massacre, oversaw one of the most brutal atrocities of the Second World War yet never faced justice. In December 1937, as Japanese forces swept across China during the Second Sino-Japanese War, one of the darkest chapters of the 20th century unfolded in Nanjing. Behind this catastrophe stood not only generals and soldiers, but a member of Japan’s imperial family: Prince Yasuhiko Asaka.Born into aristocracy in 1887, Asaka rose through the ranks of the Imperial Japanese Army and enjoyed immense prestige at court. But in November 1937, he was transferred to the front lines outside Nanjing, becoming temporary commander of Japanese forces just as the final assault began. Between 2 and 6 December, he reportedly issued the infamous order to “kill all captives,” granting official sanction to mass murder. What followed became known as the Nanjing Massacre or “Rape of Nanjing.” Over a period of six weeks, Japanese units committed atrocities on an unimaginable scale: mass executions along the Yangtze River, bayonet killings, beheadings, arson, looting, and the systematic rape of tens of thousands of women and girls. Survivors described entire neighborhoods turned into killing fields. Families were forced into incest under threat of death. Soldiers photographed victims after assaulting them. The death toll may have reached 300,000. Despite overwhelming evidence—including testimony from Japanese soldiers—Asaka was never prosecuted. When the war ended, Supreme Commander Douglas MacArthur chose to protect the imperial family for political reasons, granting immunity to all its members. General Iwane Matsui, Asaka’s superior, was executed for failing to stop the massacre. Asaka, its on-the-ground commander, lived freely. Stripped of imperial status in 1947, he retired to Atami, converted to Catholicism, played golf, and died peacefully in 1981 at age 93—never facing justice for one of history’s greatest atrocities.This episode is part of the series Fate of Top Officials of Imperial Japan.Watch the full documentary and explore hundreds of historical films at:WorldHistory.tv
