In 1663, during the reign of the fourth shogun Ietsuna TOKUGAWA and the fifth shogun Tsunayoshi TOKUGAWA, the system of the Tokugawa shogunate administration was changed from the military administration to the civilian administration; in other words, shifted from the way of kabukimono samurai to the Confucianism-based bushido (shido) (the samurai code).
