Hagakure (Kyūjitai: 葉隱; Shinjitai: 葉隠; meaning Hidden by the Leaves or Hidden Leaves), or Hagakure Kikigaki (葉隠聞書), is a practical and spiritual guide for a warrior, drawn from a collection of commentaries by the clerk Yamamoto Tsunetomo, former retainer to Nabeshima Mitsushige (July 10, 1632 – July 2, 1700), the third ruler of what is now Saga Prefecture in Japan. Tashiro Tsuramoto compiled these commentaries from his conversations with Tsunetomo from 1709 to 1716; however, it was not published until many years afterwards. Written during a time when there was no officially sanctioned samurai fighting, the book grapples with the dilemma of maintaining a warrior class in the absence of war and reflects the author's nostalgia for a world that had disappeared before he was born. Hagakure was largely forgotten for two centuries after its composition, but it came to be viewed as the definitive guide of the armed forces of the Empire of Japan during the Pacific War. Hagakure is also known as The Book of the Samurai, Analects of Nabeshima or Hagakure Analects. Source: Wikipedia (en)
