Who was Hanzo?
Hattori Hanzo (1542–1596) was a samurai officer in Tokugawa Ieyasu's service, best known for commanding a body of warriors from Iga Province. In modern films, games and comics he is the archetypal ninja. In the historical record he is a spear-carrying line commander who happened to have unusually good connections with the Iga fighting families.
His personal name was Masanari. "Hanzo" was a name used across several generations of the family, which is one reason the historical man is easy to confuse with his relatives and with later fiction.
Why is Hanzo important?
- He organised the escort that got Ieyasu across Iga Province to safety after Nobunaga's death in 1582 — the single event that made his name.
- He commanded Iga men in Tokugawa service, and his unit became the origin of the shogunate's later Iga guard.
- He is the main real-world source of the modern ninja image, which makes separating record from invention especially useful here.
- Hanzomon, a gate of Edo Castle and today a Tokyo subway station and line, is named after him.
What he actually did
Hanzo served the Tokugawa from his teens and fought in their major campaigns, including Battle of Mikatagahara. Contemporary references describe him fighting with a spear and holding a commander's stipend; he was, in structure and pay, a regular Tokugawa officer.
His family came from Iga Province, a region whose warrior households specialised in scouting, infiltration and irregular warfare and hired themselves out across central Japan. Hanzo's value to Ieyasu was that he could raise and direct those men.
The escape through Iga, 1582
When Oda Nobunaga was killed at Honnoji Incident, Ieyasu was near Osaka with only a small party, deep inside hostile country. The route home ran through Iga, where local warriors had been devastated by Nobunaga's invasion two years earlier and had every reason to kill any traveller associated with him.
Hanzo, whose family ties ran into those villages, is credited with arranging safe passage and escort. Ieyasu reached Mikawa alive. The episode is well attested in outline, though the details in later accounts vary a great deal.
Hanzo and the ninja image
The black costume, the throwing stars, the roof-running: these come from Edo-period theatre conventions and twentieth-century film and manga, not from sixteenth-century documents. Real shinobi work was gathering information, arson, infiltration and guiding armies through unfamiliar terrain, and the people who did it dressed to blend in, not to be seen.
Hanzo himself was not a shinobi in that operational sense. He was the samurai officer who employed them. The distinction is worth keeping, because almost every "ninja fact" that circulates in English traces back to entertainment rather than evidence. See Ninja and Shinobi in the Sengoku Period.
Legacy
After his death, the Iga men in Tokugawa service were organised into a formal guard unit for Edo Castle. The western gate they were stationed near became known as Hanzomon — "Hanzo's gate" — and the name survives in modern Tokyo.
His spear is preserved at Sainenji temple in Shinjuku, where he is buried. It is a large, ordinary infantry weapon: a good reminder of what he actually was.
