Often, if you take a course in business strategy, it will include the wonderful Art of War by Sun-Tzu. Sometimes you are asked to read Mushashi's Book of Five Rings, which is Japanese in origin, not Chinese like Sun-Tzu. It's more philosophical and etherial than Sun-Tzu's book, which can be compared to Von Clauswitz's "The Nature of War." But--if you study martial arts, or plan to work in Japan, have Japanese partners, or if you just enjoy learning about military philosophy as a part of business strategy, then "Bushido: The Way of the Samurai" is a fascinating book with a lot to offer the reader. In fact, this is probably one of the best books I could recommend to get to know the mindset of Japanese business leaders. Man of them come from old Samurai families, whose history and traditions go far, far back in time.
In particular, the book outlines the aspects of Bushido philosophy:
The book of course gives the meaning of Samurai rituals, including seppuku (hari-kiri) and discussing the training of a warrior. Lest you think this is old hat, business leaders in Japan today all study Kendo, the martial art of the sword and the closest to Bushido's heart.
Even women are not exempted from the Bushido code. They are expected to do their part as warriors, and women traditionally have used the naginata (halberd or pike) as a defensive weapon. It's funny to think that the naginata is considered "effeminate" and watch a Japanese sportswoman wielding that deadly blade against eight opponents during a martial arts demonstration. It's wise not to take Japanese women in business lightly. They nearly all study naginata in school.
I've worked briefly in Japan and have studied Aikido in the past. I found "Bushido" to be one of the most valuable books I own on the subject of Japanese culture and mindset, as well as an additional good book on military philosophy.
