Kantō Massacre of Koreans
The Great Kanto Earthquake of 1 September 1923 — magnitude 7.9, centred near Sagami Bay — killed roughly 105,000 people and destroyed large parts of Tokyo and Yokohama in the fires that swept the wooden urban fabric. In the chaos that followed, rumours spread rapidly through panicked crowds and were amplified by word of mouth and some police broadcasts: Koreans were said to be poisoning wells, setting fires, and organising insurrection. The rumours were false, but they ignited a sustained pogrom. Vigilante groups, often equipped with bamboo spears and swords, set up checkpoints and tested passers-by with Japanese tongue-twister pronunciations to identify Korean speakers. Japanese police units and military personnel joined or abetted the killings rather than suppressing them; some official records of the period acknowledge military involvement. Estimates of Korean victims range from 6,000 to over 10,000, with additional hundreds of Chinese and Japanese socialists killed alongside them. The Japanese government subsequently attempted to suppress documentation of the killings and prosecuted only a handful of participants, for unrelated violence. The massacre exposed the racial violence latent in Japanese imperial society and the ease with which official rumour could mobilise civilian populations against a colonial minority — a pattern Japan's wartime authorities would later mobilise at scale.
