We know that during World War II, because of the economic crisis, it was difficult to live a good life in Japan, let alone spend money on education, so militarism prevailed in Japan at this time. However, in Osaka, because the local people are good at doing business and have a wide range of knowledge, many people have a good life and a high level of ideological education. They are not bound by militarism, so they only like to make money and are not good at fighting.
Second, Osaka's cleverness is also reflected in the fact that they only like to plan their own lives. On one occasion, the Osaka Division was ordered to support other troops, and the soldiers of the unit dragged their feet and refused to go. They stopped and walked straight on. Originally, it only took four days to travel, but in the end, they only doubled. When they finally arrived, the battle was over. They are only responsible for cleaning up the battlefield. It can be seen that Osaka Division is still quite clever! It is precisely because of this that when the Japanese army surrendered unconditionally in World War II, the Japanese troops of other troops suffered heavy casualties, but the troops of Osaka Division were still full, which shows its uniqueness.
Finally, their intelligence is also reflected in treating the war with the advantage of businessmen. According to historical records, the soldiers of the Fourth Division won't be as crazy as other Japanese soldiers in the battle, and the fighting style of the Fourth Division is more like that of the US military: to maintain effective strength and not to make unnecessary sacrifices. This way of fighting was unique in the militaristic Japanese army at that time, and even violated the prevailing Bushido spirit at that time, so even the Fourth Division within the Japanese army at that time had a bad reputation. But this is precisely their clever performance, isn't it?
