A Hereditary Book on the Art of War (兵法家伝書) is a Japanese text on the theory and practice of swordsmanship and strategy, written by the samurai Yagyū Munenori in 1632. Alongside Miyamoto Musashi's The Book of Five Rings, it is one of the preeminent treatises on warfare in classical Japanese literature. Similar to Musashi's contemporary work, Munenori's has garnered appeal for its applicability beyond the warrior paradigm.
