Second General Army (Japan)

The Second General Army (第2総軍 (日本軍) Dai-ni Sōgun) was an army group of the Imperial Japanese Army responsible for the defense of western Honshū, Kyūshū and Shikoku during the final stage of Pacific War.


The Second General Army was established on April 8, 1945 with the dissolution of the guerilla warfare cells in anticipation of the projected Allied invasion of the Japanese home islands in Operation Downfall (or Operation Ketsugō (決号作戦 Ketsugō sakusen) in Japanese terminology). Although its territory encompassed all of western Japan, its primary mission was to ensure the security of southern Kyūshū, which was regarded as the most probable target for invasion. Its forces consisted mostly of poorly trained reservists, conscripted students and home guard militia.

After the fall of Okinawa, the command of the Second General Army was relocated to Hiroshima. When the atomic bomb was dropped on Hiroshima, most of the military units, logistical arms, and command staff of the Second General Army were killed. Together with the Fifth Division, Fifty-Ninth Army, and other combat divisions in the city who were also hit, an estimated 20,000 Japanese combatants were killed.

Survivors regrouped at Ujina Air Base at the outskirts of Hiroshima, where they organized relief efforts and maintained public order in Hiroshima once American occupation authorities until November 1945 to assist with the demobilization of Japanese troops.
