After the outbreak of the war of aggression against China, Osaka Division, as the main tribe of Japanese invaders, participated in some operations in North China and Central China and committed many crimes of aggression. After the Japanese attack on Pearl Harbor, most of Division A and Division B were sent to the Pacific battlefield, and Osaka Division was also sent to Bataan Peninsula. By the time Osaka Division arrived in Bataan Peninsula, the Japanese army had cut off the supply line of the American army, which had resisted for several months, and had no food and clothing, and had already lost its determination to resist.
Shortly after Osaka Division entered the war, the American and Philippine troops announced their surrender, and Osaka Division also won a great victory in vain. In the middle of the Pacific War, Osaka Division was stationed in Japan for a period of time, and was later transferred to Southeast Asia. As Osaka is a commercial city, the thinking of Osaka people is very different from that of Japanese people in other regions. During World War II, most Japanese troops believed in Bushido, and were proud of dying in the battlefield and ashamed of getting cold feet.
Undeniably, the Osaka division is really influenced by businessmen's mercenary thoughts, and it is far less militant than other divisions in Japan. After the battle in Bataan Peninsula, Osaka soldiers even started a business, selling surplus munitions to make money. After the emperor announced his surrender, the rest of the Japanese divisions tried to resist, but the Osaka division safely completed the surrender and handover without any fearless resistance. Osaka Division is the best-preserved unit of the Japanese Southern Army with the least casualties. However, it is undoubtedly ridiculous to take a one-sided view of history and blindly deny the combat effectiveness of Osaka Division.
