Explanation:

The Allies were very kin to disarm and stop from arming again the Japanese. First they took away all the arms of the Japanese and dismissed the military. But in order to stop an upraise and militarizing again, they also banned all  the military personnel from leadership roles, thus taking away their influence and authority. The reason why this was done to the Japanese was in order to totally secure the ground that they will not attack again, as the Allies wanted to focus on Europe and attack Italy and Germany, defeating them, and ending the war. Making Japan harmless was crucial for that mission to be successful.
