Bushido, literally translated "Way of the Warrior," developed in Japan between the Heian and Tokugawa Ages (9th-12th century). It was a code and way of life for Samurai, a class of warriors similar to the medieval knights of Europe. It was influenced by Zen and Confucianism, two different schools of thought of those periods. Bushido is not unlike the chivalry and codes of the European knights. "It puts emphasis on loyalty, self sacrifice, justice, sense of shame, refined manners, purity, modesty, frugality, martial spirit, honor and affection" (Nippon Steel Human Resources Development Co., Ltd. 329).
