Herrigel (1884–1955) was a German professor of philosophy, with a special interest in mysticism. From 1924 to 1929 he taught philosophy in Japan, and studied Kyūdō (the art of the Japanese bow) under a master named Awa Kenzô. Awa taught kyūdō in a way that was regarded by some as a mystical religion, called Daishadokyo. Daishadokyo was an approach to kyūdō that placed great emphasis on the spiritual aspect and differed from much of the mainstream practice at the time.
