WWII Factions: The Japanese Army
TLDRThe Imperial Japanese Army (IJA) saw significant expansion in the 1920s, with the Emperor at its helm, though the Ministry of War and General Staff Office often directed its actions. The IJA's aggressive phase began with the invasion of Manchuria in 1931 by the Kwantung Army, leading to the Second Sino-Japanese War in 1937, which marked the IJA's notoriety for brutality. The war strained the IJA's resources, necessitating increased conscription. Conflicts with the Red Army in the 1930s, notably the Nomanhan Incident, resulted in a loss of prestige, elevating the Imperial Japanese Navy. The IJA's Pacific campaign began with victories, including the capture of Hong Kong and Singapore, but shifted to a defensive stance after the Guadalcanal campaign. By 1943, shortages in supplies and starvation led to increased use of sacrificial tactics, with few surrenders at Saipan in 1944. The war's tide turned against Japan, with the U.S. reclaiming the Philippines and capturing Iwo Jima and Okinawa. The IJA, with nearly 2 million troops, prepared for a mainland defense, but the bombings of Hiroshima and Nagasaki led to Japan's surrender and the IJA's dissolution. Over 6.3 million served in the IJA from 1937 to 1945, with an estimated 1.3 million killed or missing.
