Japan's Art of War
In the early 1600's, a samurai named Miyamoto Musashi (), emerged from obscurity to mixing with the ruling class based solely on his undeniable skill in man to man combat. In a series of duels, he won against people that were thought unbeatable. At one time, using his two sword technique, he single-handedly beat over 30 samurai simultaneously attacking him with guns, arrows and swords.
He wrote an analysis of his style in a book, The Book of Five Rings (). Recently, the book has remerged as a reference and conversation point for modern Japanese and Western businessmen. It's strategies can be applied wherever there is conflict and competition occur. Like Sun Tzu's Art of War, it is written by someone with direct experience.
