Name of the real Japanese war leader during world war 2?

During WW2, when Japanese Infantrymen made a bayonet charge, they charged in the name of the Emperor. Most, if not all, historians know that the commander (Prior to the 21st Century: In any nation, of any army, of any warship) is responsible for anything that "command" does or does not do. If it does well, the COMMANDER is rewarded, not the men; if fails, the COMMANDER is disciplined, not the men. The Emperor was the commander; his Lieutenants were the Field Generals and Fleet Admirals.
