What is a Ninja?
Practitioners of ninjutsu (the art of stealth, camouflage, and sabotage) are referred to as ninja.
According to the Japanese ancient text "Chronicles of Omi," ninjas can infiltrate enemy castles, observe and listen for secrets, and inform those on their own side.
There are many theories about the origins of ninjutsu. However, it is generally believed to have originated in the latter half of the 13th century to resist the feudal estates' oppressive powers. The names for these individuals varied by region, with terms like "Rappa," "Suppa," and "Kusa."
After entering the Muromachi Period (1336-1573), the influence of temples and shrines managing the estates weakened. This caused active bandits to transition into "Jizamurai" (local samurai).
By the Warring States Period (1467-1603), these individuals became mercenaries for warlords such as the Oda and Tokugawa clans, participating in battles in areas like Kyoto and Nara.
They would infiltrate enemy camps to set fires, cause destruction, conduct night raids, lay ambushes, and gather intelligence. The most important task was to report the status of the enemy back to their lord.
During this time, ninjas were referred to as "shinobi." The term "ninja" became popularized in the 1950s due to its use in novels and other materials.

Among the most famous stories is that of future shogun Tokugawa Ieyasu escaping from Osaka's Sakai City back to Okazaki after the Incident at Honnoji Temple (1582), escorted by Iga and Koga ninjas as they traversed Iga to return.
During the Edo Period (1603-1868), there was peace, which drastically decreased opportunities for ninjas to engage in combat. Therefore, their primary duties shifted to intelligence gathering and security.
The Tokugawa shogunate notably employed the Iga-born general Hattori Masanari (Hanzo III, Iwami no Kami), even naming one of the gates of Edo Castle after him. This is where the present-day Tokyo location of Hanzomon comes from.
Entering the Meiji Era (1868-1912) and establishing a new government system, ninjas lost even more operational space, ultimately drawing to a close.
Famous Ninjas in History
Hattori Hanzo
Hattori Hanzo refers to the head of the Hattori clan that was active under the Tokugawa family from the Warring States Period to the Edo Period.
Each successive head was called Hattori Hanzo, but the only true ninja among them was the Hanzo II, Hattori Masanari (Oni no Hanzo), who spread the name Hattori Hanzo far and wide.
Ideura Morikiyo
A ninja who served the Sanada clan during the Warring States Period, Ideura Morikiyo is the prototype for the character Kirigakure Saizo in the novel Sanada Ten Braves.
Fuma Ninjas
The Fuma ninjas served the Hojo clan during the Warring States Period and are one of the prototypes for the literary character Fuma Kotaro.
Ninja Schools
Iga and Koga are two Japanese provinces that are not far from Kyoto. Both areas are surrounded by mountains that form a natural stronghold, which naturally delineates local powers. Below are two of the most famous ninja schools.
Iga-ryu (The Iga School)

Ninjas belonging to the Iga-ryu (The Iga School), originating from Iga Province (now Iga City in Mie Prefecture), excel in rapid movement in mountainous areas.
They are characterized by their use of incantations and gunpowder-based fire techniques. The training methods of Iga ninjas are unique and rigorous, cultivating exceptional ninjas.
The organization of the Iga-ryu has a hierarchical structure primarily guided by the opinions of the three upper-ranking families—Hattori, Momochi, and Fujibayashi.
Although there is a system of consensus, most of the time, they still adhere to the opinions of the three upper-ranking families. The relationship between Iga ninjas and their employers is based on monetary contracts, and situations sometimes arise where employers are adversaries.
Koka-ryu (The Koka School)
Continuing the history of Koka-ryu ninjas' medical proficiency, the existing Koka-ryu ninja residence holds a pharmaceutical certification
The Koka-ryu ninjas, separated from the Iga-ryu by just one mountain, are based in Koga Province (now Koka City in Shiga Prefecture).
They typically gather intelligence through farming and selling medicines and are known for their skills in magic and medicinal use. Koga ninjas have a long history of using medicine, and there are still many pharmaceutical companies in Koka City today.
The organization of the Koka-ryu is based on a consensus system called "So," which does not distinguish between ranks. Proposals related to the entire district are decided by majority vote, differing from the Iga-ryu's structure.
Another difference is that the Koka-ryu maintains a loyal master-servant relationship with a single lord.
Comparison of Iga-ryu vs Koka-ryu
Many believe Iga-ryu and Koka-ryu are bitter enemies, but this impression originated from later fictional portrayals. In reality, there was no such animosity between the two.
Iga-ryu | Koka-ryu | |
Expertise in Ninjutsu | Fire techniques related to gunpowder Incantations |

Internal Organizational Structure | Hierarchical structure, primarily governed by the three upper-ranking families | Consensus-based organization called "So," with decisions made by the majority vote |

I used to live in Japan and managed to conquer 78 out of the 100 famous castles and 12 existing castle towers in 8 years. As a history enthusiast, I also have a passion for baseball and Japanese dramas, which have driven me to visit all 47 prefectures. I hope to convey not only the scenery of Japan but also more of its culture and way of life.
