Western District Army
Military unit
The Western District Army (西部方面軍, Seibu-hōmen gun) was a regional command of the Imperial Japanese Army (equivalent to a field army) responsible for the defense of the Kantō region and western Honshū, Shikoku and Kyūshū during the Pacific War. It was one of the regional commands in the Japanese home islands reporting to the General Defense Command.

The Western District Army was established on 2 August 1937 as part of the regional realignment of the Imperial Japanese Army as the Western Defense Command (西部防衛司令部, Seibu Boei Shireibu). It was essentially a home guard and garrison responsible for recruitment and civil defense.
On 1 August 1940, it was renamed again as the Western Army (西部軍, Seibu-gun), which became the Western District Army on 1 February 1945.
The Western District Army existed concurrently with the Japanese 16th Area Army and the Japanese 15th Area Army, which were tasked with organizing the final defenses of Kyūshū and Shikoku against the expected American invasion of the Japanese home islands. The Western District Army assumed all administrative functions, whereas the individual area armies were operational combat commands.
The Western District Army remained active for several months after the surrender of Japan to help maintain public order until the arrival of the American occupation forces, and to oversee the final demobilization and dissolution of the Imperial Japanese Army.
