In Japan, the Bushido was not created by one great man as like in a particular religion, but it was the moral culture of the warrior to be fostered, naturally cultured, polished, and established as a rule for the warrior to survive in Japan's long feudal society. However, Bushido, which is widely known both in Japan and in the world today, is a Bushido that is far from the real state of the warriors and their spirit world. The formation of today's Bushido can be seen as a result of the controversy over the Bushido, which was heated during the Meiji Era. The debate on the Bushido in Meiji Era took place between intellectuals who had claimed for the emperor and Christians who argued for Christian Bushido. But the Bushido for the emperor, which overwhelmingly had dominated at that time, disappeared like a bubble after World War II. Since then, Bushido, which was centered on Christians, remains to this day, leading Japan's Bushido. This paper aims to study the trend of the controversy over Bushido during the Meiji Era, focusing on the Christian Bushido, which has remained until today and distorted it.
