Ninjutsu refers to the specialized techniques and skills used by covert operatives in pre-modern Japan. These operatives were known as ninja or shinobi. They acted as intelligence gatherers and irregular warfare specialists. While many people think of them as simple mercenaries, historical texts suggest they were more complex. Some ninja scrolls contain information about daily needs and even mining techniques. This shows that ninjutsu was built on the fundamental principle of adaptation.

The training for these skills was intense and began in childhood. Young ninja studied survival and scouting techniques alongside physical training. They practiced long-distance running, climbing, swimming, and stealthy walking. They also gained knowledge about poisons, explosives, and medical first aid. For example, an Iga ninja once used a "black medicine" to stop bleeding for Ii Naomasa. Knowledge of common professions was also vital. This allowed them to use disguises to move through society unnoticed.

History shows that spying in Japan dates back to Prince Shōtoku (572–622). The first open use of ninjutsu in a military campaign occurred during the Genpei War (1180–1185). During this time, Minamoto no Kuro Yoshitsune chose specific warriors to serve as shinobi. Later, Kusunoki Masashige used these methods during the Kenmu Restoration (1333–1336). A major turning point occurred in 1162. A samurai named Daisuke Togakure lost his lands and title. He traveled to the mountains of southwest Honshu and met a Chinese warrior-monk named Kain Doshi. Together, they formulated the guerrilla art of war known as ninjutsu.

Ninjutsu was further refined during the Nanboku-cho period and the Sengoku period. Many rising warlords used ninja for intelligence and secret raids. In the Kōka and Iga provinces, local samurai called jizamurai used guerrilla warfare to protect their lands. These jizamurai operated as independent confederacies known as the Kōka and Iga ikki. They remained powerful until Oda Nobunaga conquered Kōka in 1574 and Iga in 1581. After these conquests, daimyō could no longer recruit professional ninja. Instead, they were forced to train their own shinobi.

Techniques in ninjutsu were often grouped by natural elements. For example, katon-no-jutsu, or fire techniques, included distracting guards by starting fires. Mokuton-no-jutsu, or wood techniques, involved climbing trees and using foliage for camouflage. Suiton-no-jutsu, or water techniques, used duckweed to hide movement underwater. Finally, doton-no-jutsu, or earth techniques, involved curling into a ball to look like a stone.

Disguises were a central part of any covert operation. Ninja often dressed as merchants, entertainers, or fortune tellers. They might also wear the robes of Buddhist priests to hide weapons like the tantō. Some used the attire of mountain ascetics, or yamabushi, to travel freely between political boundaries.

While popular media often shows ninja in black, they likely wore navy blue farmer's clothes. Black clothing may have been an artistic convention used in theater to simulate invisible movement.

Ninja carried a wide variety of specialized equipment. They used ropes, grappling hooks, and even small collapsible boats. The kunai was a heavy, pointed tool used primarily for gouging holes in walls. They also used mizugumo, which were wooden shoes designed to distribute weight on water. Although they had many tools, the Bansenshūkai manual advised against being overburdened. It stated that a successful ninja uses one tool for multiple tasks.

Many different schools, or ryū, have taught unique versions of ninjutsu. The Togakure-ryū was founded by the descendants of Daisuke Togakure. Later, important manuals were written, such as the Ninpiden (1655) and the Bansenshūkai (1675). Modern schools like the Bujinkan arose in the 1970s. However, the authenticity of these modern styles is often debated. The last authentic heir, Jinichi Kawakami, chose to end his line in 2012. He stated that the art has no practical place in the modern age.
