context_page_description: Samurai were the hereditary military nobility and officer caste of medieval and early-modern Japan from the 12th century to their abolition in the 1870s. They were the well-paid retainers of the daimyo. They had high prestige and special privileges such as wearing two swords. They cultivated the bushido codes of martial virtues, indifference to pain, and unflinching loyalty, engaging in many local battles. During the peaceful Edo era they became the stewards and chamberlains of the daimyo estates, gaining managerial experience and education. In the 1870s samurai families comprised 5% of the population. The Meiji Revolution ended their feudal roles, and they moved into professional and entrepreneurial roles. Their memory and weaponry remain prominent in Japanese popular culture.
context_section_description: In the 13th century, Hōjō Shigetoki wrote: "When one is serving officially or in the master's court, he should not think of a hundred or a thousand people, but should consider only the importance of the master." Carl Steenstrup notes that 13th and 14th century warrior writings (gunki) "portrayed the bushi in their natural element, war, eulogizing such virtues as reckless bravery, fierce family pride, and selfless, at times senseless devotion of master and man". Feudal lords such as Shiba Yoshimasa (1350–1410) stated that a warrior looked forward to a glorious death in the service of a military leader or the emperor: "It is a matter of regret to let the moment when one should die pass by ... First, a man whose profession is the use of arms should think and then act upon not only his own fame, but also that of his descendants. He should not scandalize his name forever by holding his one and only life too dear ... One's main purpose in throwing away his life is to do so either for the sake of the Emperor or in some great undertaking of a military general. It is that exactly that will be the great fame of one's descendants."
  In 1412, Imagawa Sadayo wrote a letter of admonishment to his brother stressing the importance of duty to one's master. Imagawa was admired for his balance of military and administrative skills during his lifetime, and his writings became widespread. The letters became central to Tokugawa-era laws and became required study material for traditional Japanese until World War II:
  "First of all, a samurai who dislikes battle and has not put his heart in the right place even though he has been born in the house of the warrior, should not be reckoned among one's retainers ... It is forbidden to forget the great debt of kindness one owes to his master and ancestors and thereby make light of the virtues of loyalty and filial piety ... It is forbidden that one should ... attach little importance to his duties to his master ... There is a primary need to distinguish loyalty from disloyalty and to establish rewards and punishments."
  Similarly, the feudal lord Takeda Nobushige (1525–1561) stated: "In matters both great and small, one should not turn his back on his master's commands ... One should not ask for gifts or enfiefments from the master ... No matter how unreasonably the master may treat a man, he should not feel disgruntled ... An underling does not pass judgments on a superior."
  Nobushige's brother Takeda Shingen (1521–1573) also made similar observations: "One who was born in the house of a warrior, regardless of his rank or class, first acquaints himself with a man of military feats and achievements in loyalty ... Everyone knows that if a man doesn't hold filial piety toward his own parents he would also neglect his duties toward his lord. Such a neglect means a disloyalty toward humanity. Therefore such a man doesn't deserve to be called 'samurai'."
  The feudal lord Asakura Yoshikage (1428–1481) wrote: "In the fief of the Asakura, one should not determine hereditary chief retainers. A man should be assigned according to his ability and loyalty." Asakura also observed that the successes of his father were obtained by the kind treatment of the warriors and common people living in domain. By his civility, "all were willing to sacrifice their lives for him and become his allies."
  Katō Kiyomasa was one of the most powerful and well-known lords of the Sengoku period. He commanded most of Japan's major clans during the invasion of Korea. In a handbook he addressed to "all samurai, regardless of rank", he told his followers that a warrior's only duty in life was to "grasp the long and the short swords and to die". He also ordered his followers to put forth great effort in studying the military classics, especially those related to loyalty and filial piety. He is best known for his quote: "If a man does not investigate into the matter of Bushido daily, it will be difficult for him to die a brave and manly death. Thus it is essential to engrave this business of the warrior into one's mind well."
