The main tactic used was to fly in groups of three: two would operate as decoys, drawing the fire of anti-aircraft guns, while the third made its bombing pass. It would then swap places with one of the decoys, until all the planes had delivered their lethal cargo. They were so accurate, the Germans spread rumours that the women pilots had been injected with drugs to give them cat-like night vision. But their stamina was equally tested: the limited capacity of the planes often forced them to fly fifteen or more sorties per night, often under heavy fire. Their craft had no radios, no radar, and the pilots didn’t bother with parachutes, because the low altitude at which they operated would have rendered them useless.
Kokutai , meaning the uniqueness of the Japanese people in having a leader with spiritual origins, was officially promulgated by the government, including a text book sent about by the Ministry of Education.  The purpose of this instruction was to ensure that every child regarded himself first of all as a Japanese and was grateful for the "family polity" structure of government, with its apex in the emperor.  Indeed, little effort was made during the course of the war to explain to the Japanese people what it was fought for; instead, it was presented as a chance to rally about the emperor.
