In eighteenth-century Japan, Tsunetomo Yamamoto created the Hagakure, a document that served as the basis for samurai warrior behavior. Its guiding principles greatly influenced the Japanese ruling class and shaped the underlying character of the Japanese psyche, from businessmen to soldiers. Bushido is the first English translation of the Hagakure. This work provides a powerful message aimed at the mind and spirit of the samurai warrior. It offers beliefs that are difficult for the Western mind to embrace, yet fascinating in their pursuit of absolute service. With Bushido, one can better put into perspective Japan’s historical path and gain greater insight into the Japan of today.
