"Codex Bushido" (also translated as "The Way of the Samurai" or "The Art of the Samurai"), or in Japanese - "Hagakure" ("Hidden in the Leaf"), was written by Yamamoto Tsunetomo (1659 - 1719). He was a samurai from the Saga clan on the island of Kyushu. After the death of his master Nabeshima Naoshige, Yamamoto became a monk and devoted his entire life to generalizing the principles of the Way of the Samurai, as well as popularizing the principles of honor and loyalty to his master. Miyamoto Musashi's The Book of Five Rings ranks first in many swordsmanship bibliographies and is a unique strategy textbook in that the principles it teaches apply to single combat as well as army combat. Mousasi claims that it is "a manual for those who want to study strategy", the meaning of which the reader may not grasp immediately. How well a person learns them for himself depends on how carefully a person studies the principles given in the book. Translated into Ukrainian by Yaroslav Myshanych.
