General Iwane Matsui

Biography

Iwane Matsui was born on July 27, 1878, in Aichi prefecture, Japan. A career military officer who rose to become one of Japan's most senior generals, he is remembered primarily as the commander responsible for the Nanjing Massacre — an event he later claimed he tried to prevent, and for which he was executed as a war criminal in 1948. Matsui graduated from the Imperial Japanese Army Academy and spent his career rising through the ranks, serving in the Russo-Japanese War and in various staff and command positions. By the 1930s he was a general officer with a reputation as a China specialist who had cultivated relationships with Chinese political figures. He believed in Pan-Asian solidarity and saw himself as a friend to China — an attitude that makes his role in the events of December 1937 all the more complex and contested. Matsui was recalled from retirement in 1937 to command the Shanghai Expeditionary Force. After the brutal three-month Battle of Shanghai, his forces pursued the retreating Chinese army toward Nanjing. He entered Nanjing on December 17, 1937, four days after the city fell, in a triumphal procession. What had already begun — and what continued for six weeks — was a systematic campaign of murder, rape, looting, and destruction that killed between 200,000 and 300,000 Chinese civilians and disarmed prisoners of war. Matsui's command responsibility for the Nanjing Massacre was the subject of intense debate at his trial before the International Military Tribunal for the Far East. The prosecution argued he knew the massacre was occurring and failed to stop it. The defense argued he was ill during much of the critical period and issued orders against misconduct that his subordinates ignored. The tribunal found him guilty of war crimes under the doctrine of command responsibility. He was executed by hanging on December 23, 1948, at Sugamo Prison in Tokyo. Until his death, Matsui maintained that he had tried to restrain his troops and was heartbroken by the atrocities. He built a Buddhist shrine at his home called Koa Kannon, where bones of Chinese war dead were interred alongside Japanese, and prayed there daily. Whether this reflected genuine remorse, an attempt at spiritual atonement, or a means of managing his own guilt remains debated by historians.
