The Iga Ninjas were covert agents from the Iga Province in Japan, known for their skills in espionage, sabotage, and guerrilla warfare during the feudal period. They were part of a larger group of shinobi, or ninjas, who specialized in stealth and unconventional tactics. Iga Ninjas often worked for samurai and feudal lords, gathering intelligence and carrying out secret missions. Their training included martial arts, disguise, and the use of various tools and weapons, such as shuriken and smoke bombs, to aid in their operations.
