Armies of the Imperial Japanese Army

on maneuvers The was the highest level in the organizational structure of the Imperial Japanese Army. It corresponded to the army group in western military terminology. Intended to be self-sufficient for indefinite periods, the general armies were commanded by either a field marshal or a full general. The initial General Army was the Japanese Manchurian Army, formed from 1904 to 1905 during the Russo-Japanese War as a temporary command structure to coordinate the efforts of several Japanese armies in the campaign against Imperial Russia. In terms of a permanent standing organization, the Japanese Army created the Kantōgun, usually known in English as the Kwantung Army, to manage its overseas deployment in the Kwantung Territory and Manchukuo from 1906. Subsequent general armies were created in response to the needs of the Second Sino-Japanese War and World War II, in which increased overseas deployment called for an organizational structure that could respond quickly and autonomously from the Imperial Japanese Army General Staff in Tokyo. As a result, Japanese forces were re-organized into three separate overseas operational commands: (Manchuria, China and Southeast Asia), with the Japanese home islands forming a fourth. Towards the end of World War II, the home island command (i.e. the General Defense Command) was restructured geographically into the First General Army in the east, Second General Army in the west, and the Air General Army in charge of military aviation. With the official Japanese surrender in September 1945, all of the general armies were dissolved, except for the First General Army, which continued to exist until November 30, 1945, as the 1st Demobilization Headquarters. ==Area Armies==
