Yokohama, and the surrounding areas.
On 1 August 1935, the Tokyo Defense Headquarters was renamed the Eastern Defense Command. On 1 August 1940, it was renamed again as the Eastern Army, which became the Eastern District Army on 1 February 1945.
The Eastern District Army existed concurrently with the
Japanese 12th Area Army, which was tasked with organizing the final defenses of Tokyo against the expected
American invasion of the Japanese home islands.
The Eastern District Army played an especially significant role in combating the
15 August 1945 attempted coup d'etat of Major
Kenji Hatanaka, who sought to prevent the
Emperor's announcement of Japan's surrender from being broadcast. At the time, the commander of the Eastern District Army was Lieutenant General
Shizuichi Tanaka.
Support of the Eastern District Army was essential to Hatanaka's plan to take over the
Imperial Palace, and so Hatanaka exhorted General Tanaka to aid him. Tanaka refused, and later told his men to ignore Strategic Order 584, forged by Hatanaka and ordering the Eastern District Army to seize and defend the
Imperial Palace; in short, to aid in the
coup. Rather than send in his men to defeat the rebels by force, Tanaka traveled to the Imperial Palace and spoke to Hatanaka and the other rebel leaders personally, haranguing them, and putting an end to the rebellion.
The Eastern District Army remained active for several months after the
surrender of Japan
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy ...
