The Ninja were the shadow warriors of feudal Japan—masters of stealth, espionage, and deception who operated in the unseen world of political intrigue and warfare. Emerging during Japan’s turbulent Sengoku period, these covert agents specialized in reconnaissance, sabotage, and assassination, often serving rival warlords in their struggles for power. Far from the myths of supernatural powers, the real ninja relied on discipline, disguise, and cunning to outwit their enemies. From the hidden villages of Iga and Kōga came generations of spies and saboteurs whose tactics would become legendary. In this episode, we unveil the origins, methods, and enduring mystique of the Ninja—the silent blades that shaped the shadows of Japanese history. #history #ancienthistory #historydocumentary #historyforsleep
