The word ninja comes from two kanji. Another name for them was shinobi. This word means to hide or steal away.

Many ninja lived in the Iga and Kōga areas. These places had high mountains. The mountains made it hard for others to find them.

The ninja were special agents in old Japan. They often worked as spies or scouts. Many people think they were assassins, but there is little evidence for this. They mostly focused on secret work for money. This work was different from the way samurai lived. Their skills were used to help leaders during times of war. They could also act as agitators or surprise attackers. This made them very useful in many different situations.

Ninja used many clever ways to do their jobs. They practiced a way of fighting called ninjutsu. Some old books describe many different fighting techniques. One book lists 48 specific points for their training. They learned how to make tools from bamboo called makibishi. They also made special footwear that made no sound. They even learned how to listen for very small sounds.

These skills helped them stay hidden and safe.

The history of these agents goes back a long time. Some stories link them to a prince named Yamato Takeru. Others mention a spy named Otomono Sahito from the 6th century. In the year 1162, a man named Daisuke Togakure moved to the mountains. He worked with a warrior-monk named Kain Doshi. Together, they helped create the art of ninjutsu. Later, his family started a ninja school called the Togakureryu.

Many ninja came from the Iga and Kōga regions. These areas had high mountains that were hard to reach. This helped the ninja groups stay secret. In the Iga province, people lived in organized clans. They had different ranks within their groups. A jōnin was a high leader who hired others. A chūnin was an assistant to the leader. A genin was a lower person who did the actual missions.

These groups were very active during the Sengoku period. Between 1485 and 1581, leaders often hired them for war. They were great at night attacks and ambushes. In 1560, a group of eighty Kōga ninja helped a leader named Tokugawa Ieyasu. They worked to protect him during a dangerous journey. Later, after the Tokugawa shogunate began, the ninja faded away. Some even served as bodyguards for the new leaders.

The ninja were specialized agents in pre-modern Japan. They functioned primarily as spies, scouts, and infiltrators. While popular culture often portrays them as assassins, historical evidence for this is scarce. Instead, they were professional mercenaries who traded their secretive services for money.

This work was often done without the pursuit of honor or glory. This social role set them apart from the traditional samurai class.

To perform these tasks, ninja practiced a specialized system of warfare called ninjutsu. This involved many technical skills designed for stealth and survival. Historical manuals, such as the Kanrin Seiyō, detail specific training points. For instance, they learned to create makibishi, which are tools made from bamboo. They also developed footwear that allowed them to move without making sound.

Other techniques included listening for tiny sounds and using kuji-kiri to prevent dogs from barking.

The term "ninja" uses the kanji characters for "nin," meaning to hide or forbear, and "ja," meaning person. In Japan, they are also frequently called shinobi. This comes from the term shinobi-no-mono.

Historically, many different regional names were used to describe these agents. Some people called them monomi, meaning "one who sees." Others used the term nokizaru, which means "macaque on the roof." These names reflected the various ways people viewed their stealthy activities.

Tracing the origins of ninja involves both legend and documented history. Some stories link them to the 2nd-century prince Yamato Takeru.

However, these early accounts are likely not connected to the later mercenary groups. A more concrete history began around the 12th century. In 1162, a man named Daisuke Togakure moved to the mountains of southwest Honshu. He collaborated with a Chinese warrior-monk named Kain Doshi. Together, they formalized the guerrilla tactics that became known as ninjutsu. Daisuke's descendants later founded the Togakureryu, or the first ninja school.

During the Sengoku period, ninja organized themselves into highly structured groups. They often operated within specific territories and followed a clear rank system. At the top was the jōnin, or "upper person," who managed the group and hired out mercenaries. Below them were the chūnin, or "middle persons," who acted as assistants. The lowest rank was the genin, or "lower person." These genin were field agents drawn from the lower classes to carry out actual missions.

They filled roles such as kanchō (spies), teisatsu (scouts), kishu (surprise attackers), and konran (agitators).

The most famous ninja clans originated in the Iga and Kōga regions. These areas were located in remote, mountainous provinces. The inaccessibility of these mountains likely helped the groups develop in secret.

Between 1485 and 1581, daimyōs frequently hired Iga professionals for siege warfare, known as shirotori. This included specialized skills like night attacks and ambushes. The Kōga and Iga clans even formed a formal alliance around 1560. However, this era of independence ended when the leader Oda Nobunaga invaded Iga in 1581.

Despite the violence of these invasions, some ninja found new roles under the Tokugawa shogunate. After the Tokugawa era began, many ninja faded into obscurity. Some survivors, such as Hattori Hanzō, served as bodyguards for the Tokugawa leaders. In the early 1600s, a leader named Tōdō Takatora employed Iga-ryū ninja. He also used a class of part-time samurai called Musokunin. These individuals worked as farmers during times of peace but took up arms during war.

This transition shows how the specialized skills of the ninja were integrated into the new social order of Japan.
