What made them such warriors? The Japanese call it bushido, the code of the samurai, or Nippon seishin, the spirit of Nippon. I believe it was systematic indoctrination in the cult of emperor worship, and in their racial superiority as a chosen people who could conquer all. They were convinced that to die in battle for the emperor meant they would ascend to heaven and become gods, while their ashes were preserved at the Yasukuni Shrine in the suburbs of Tokyo.
