History
The area around Hanzō was part of the ancient Iga Province, which encompassed much of the eastern part of Hasukuni island. The area where Hanzō currently is was originally known as Ishiura. During the Kōya Period, Iga Province experienced a mass peasant uprising around 940, displacing the original governors of the province, the Togashi Clan, and forming a "peasant's realm" with a stronghold at modern-day Ijō.

In 1020, the Hattori Clan, who were originally vassals of the Atagi Clan in Harukuni, were ordered to carry out a campaign to wipe out the peasant rebels. As a reward for their victory, the Hattori Clan were promoted and granted ownership of Iga Province by the Atagi. In 1060, Lord Hattori Ujikage built Hanzō Castle at its current site. Backed by high hills and flanked on two sides by rivers, it was a natural fortress, around which a castle town developed. This town came to be known as Hanzō by the 12th century.

During the Mizuho War that began in 1127, the Hattori Clan initially followed their Atagi masters and carried out a campaign against the Hamuro Clan that occupied Nabari Province on Hasukuni. However, the Hattori later aligned themselves with Tsugunaga Atsumochi's coalition and achieved independence from the Atagi Clan, which was in a decline following their defeat by the Tsugunaga coalition. Hanzō remained the capital of the Hattori clan's domain, which grew to encompass all of Hasukuni.
