Bushido: The Soul of Japan by Inazo Nitobe

Bushido: The Soul of Japan written by Inazo Nitobe was one of the first books on samurai ethics that was originally written in English for a Western audience, and has been subsequently translated into many other languages (also Japanese). Nitobe found in Bushido, the Way of the Warrior, the sources of the virtues most admired by his people: rectitude, courage, benevolence, politeness, sincerity, honor, loyalty and self-control, and he uses his deep knowledge of Western culture to draw comparisons with Medieval Chivalry, Philosophy, and Christianity.
