The Bushido Code or Hagakure (Hidden in Leaves) was written by Yamamoto Tsunetomo (1659-1719), a samurai from the Saga clan on the island of Kyushu. After the death of his lord Nabeshima Naoshige, Yamamoto became a monk and devoted his entire life to summarising the principles of the Way of the Samurai, as well as honour and loyalty to his lord.
