«Bushido Code» (also translated as «The Way of the Samurai» or «The Art of the Samurai»), or in Japanese, «Hagakure» («Hidden in a 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 lord Nabeshima Naoshige, Yamamoto became a monk and devoted his entire life to summarising the principles of the Way of the Samurai and promoting the principles of honour and loyalty to his lord. Miyamoto Musashi's The Book of the Five Rings is ranked first in many bibliographies on the art of fencing and is a unique textbook on strategy, as the principles set out in it apply to both individual fights and battles between armies.

Musashi claims that this is a — «guide for those who want to study strategy», the meaning of which may not be immediately comprehended by the reader. How closely a person studies the principles in the book depends on how well he or she learns them for himself or herself.
