On this day, 75 years ago, on June 6, 1950 (April 21, 1950 in the lunar calendar), Japan's red purge began. On June 6, 1950, the U.S. occupation authorities ordered the suppression of Japanese Communists and their sympathizers, known in history as the Red Purge. In order to implement the "Cold War" policy and turn Japan into an anti-communist fortress, the United States secretly formulated a plan to purge the Reds. In 1949, the "Dodge Route" was implemented to rectify administrative and corporate personnel, focusing on purging Communist Party members and their sympathizers. On May 3, 1950, MacArthur issued a statement implying that the Communist Party was illegal. On June 6 and 7, he successively ordered Shigeru Yoshida's government to deprive 24 members of the Central Committee of the Communist Party of Japan and 27 members of the Akashi newspaper of their public positions, and dispatched police to surround the headquarters of the Communist Party of Japan. On June 26, the Red Flag newspaper was ordered to suspend publication for 30 days. On July 28, the purge was carried out in newspapers, radio stations and other institutions, and subsequently expanded to government agencies and private enterprises. More than 21,000 Japanese Communist Party members and sympathizers were laid off. The Japanese Communist Party was forced to fight underground.
