Hattori Kazutada

Who They Were

Hattori Kazutada (服部一忠) was a samurai and daimyo whose career spanned the violent transition from the Muromachi period into the unification of Japan under Oda Nobunaga and Toyotomi Hideyoshi. He is remembered chiefly for a single act of reckless courage at the Battle of Okehazama in 1560, when he became the first of Nobunaga's men to charge Imagawa Yoshimoto personally. He survived the wound he took in that attack and went on to serve two of the three great unifiers of Japan, ending his life as a castle lord with an income of 35,000 koku — and then as a casualty of the political purge that followed Toyotomi Hidetsugu's fall.

He was also known by two other names: Hattori Koheita (服部小平太) and Hattori Unemenokami (服部采女正). The second of these is a court title rather than a personal name, a common convention among samurai of rank.

Life and Career

Kazutada was born in Owari Province, in the centre of Japan's main island, and entered the service of Oda Nobunaga as a page. His first recorded action was at the Battle of Okehazama in 1560, where Nobunaga's small force destroyed the army of Imagawa Yoshimoto against overwhelming odds. Kazutada fought as a pikeman, and during the fighting he was the first of Nobunaga's men to mount a personal attack on Imagawa Yoshimoto himself. He received a sword cut across the legs and was on the point of being killed when Mōri Yoshikatsu came to his rescue and killed Yoshimoto. Nobunaga rewarded him for his part in the victory.

Little is recorded of his service in the years that followed. After Nobunaga's assassination, Kazutada transferred his allegiance to Toyotomi Hideyoshi, the general who completed the unification of Japan. In 1585 he was awarded lower fifth court rank, a formal mark of standing at the imperial court.

Following the Battle of Odawara in 1590, which ended the power of the Hōjō clan, Kazutada was granted Matsuzaka Castle in Ise Province, with revenues of 35,000 koku. A koku (石) is a measure of rice roughly sufficient to feed one person for a year, so this figure represents a substantial domain. He was also appointed to assist Toyotomi Hidetsugu, Hideyoshi's proclaimed successor.

He fought in the Bunroku Campaign in Korea between 1592 and 1593, and successfully took the Korean capital of Seoul. In 1595 he was purged along with other supporters of Hidetsugu, and was forced to commit seppuku, the ritual suicide by disembowelment.

Why They Matter

Kazutada's career traces the whole arc of Japan's unification era in miniature. He began as a page in a provincial warlord's household, made his name in the desperate gamble at Okehazama, and ended as a castle-holding daimyo under the regime that completed what Nobunaga had begun. His reward of Matsuzaka Castle and 35,000 koku shows how the new order redistributed land to those who had served it, and how quickly a samurai could rise through military service.

His death is equally instructive. The purge of 1595, in which Hidetsugu's adherents were eliminated, demonstrates that by the 1590s political survival depended less on battlefield performance than on proximity to the right claimant. Kazutada had fought and won in Korea, but his association with Hidetsugu was enough to end him. The fate of men like him shaped the rigid, hereditary social structure that the Tokugawa shogunate would impose after 1600.

The Name in Japanese

The full name is written 服部一忠. It is read in kana as はっとり かずただ, and in romaji as Hattori Kazutada. The family name comes first, as is standard in Japanese.

服 (read はっ, hat- in this name) — the character means "clothing" or "to wear." In the surname 服部 it refers to a hereditary occupational group, the Hattori, whose name is traditionally associated with weaving and with the making of cloth for the court.

部 (read とり, -tori) — this character means "part," "section," or "department." In ancient Japan it was appended to names of occupational groups bound to serve the court, so 服部 as a whole originally denoted a guild of cloth-workers. The reading はっとり is irregular and must simply be learned; it does not follow from the individual characters.

一 (read かず, kazu-) — the numeral "one." In personal names it is very often read かず rather than the more familiar いち.

忠 (read ただ, -tada) — meaning "loyalty," "devotion," or "faithfulness." It is one of the most common closing elements in samurai given names, and it carried obvious weight in a warrior culture that placed a premium on service to one's lord.

So the given name 一忠, Kazutada, can be understood as something like "one" plus "loyalty" — a name that reads almost as a job description for a retainer. Note also the alternative name Koheita (小平太): 小 means "small," 平 is a common name element, and 太 is a suffix used in male names. The title Unemenokami (采女正) was an honorary court office, with 采女 referring to female attendants of the imperial household and 正 meaning "chief" or "head."

Legacy

Kazutada left no enduring institutional legacy. His domain passed from him with his death, and his principal fame rests on a few minutes at Okehazama in 1560, where his impetuous charge nearly cost him his life and helped open the way for Mōri Yoshikatsu to kill Imagawa Yoshimoto. That single episode secured him a place in accounts of Nobunaga's rise.

His son, Ōsaki Katsunaga, is recorded as his child, carrying the family line into a different surname. For students of Japanese, the name 服部一忠 is a useful case study in how samurai names work: an occupational surname with an irregular reading, a given name built from a numeral and an abstract virtue, and a set of alternative names and court titles that a single historical figure might be known by.
