Combines material previously published as Warrior 29: Ashigaru 1467-1649, Warrior 64: Ninja AD 1460-1650, Warrior 70: Japanese Warrior Monks AD 949-1603, with a new section on Samurai, new images, and a new introduction and conclusion. The samurai remain the best known warriors of medieval Japan, but they were by no means the only fighting elite. There were the ashigaru, who were first recruited to swell army numbers but later became a vital part of any samurai force. Trained to protect their monasteries, warrior monks were formidable enemies, mastering a range of martial traditions. Finally, the Ninja catered to an increasing demand for spies, informants and sometimes assassins, developing the arts of armed and unarmed combat and explosives.

Stephen Turnbull is recognized as one of the world's foremost military historians of the medieval and early modern periods.
