Ōta Sukenobu

Who They Were

Ōta Sukenobu (太田 資順) was a daimyō — a hereditary feudal lord — of mid-Edo period Japan. He lived from 1762 until November 24, 1808, and held the rank of samurai. He was the third lord of Kakegawa Domain, a territory in Tōtōmi Province, which corresponds to modern-day Shizuoka Prefecture. He was also the seventh hereditary chieftain of the Kakegawa-Ōta clan, the family line that governed the domain.

The Ōta were a warrior house whose position rested on land, rice, and service. A daimyō in the Edo period was not simply a landowner: he was a military governor whose domain was assessed in rice yield, whose movements were regulated by the shogunate, and whose title passed from father to heir within a single family line. Sukenobu inherited all three of those things — the domain, the clan headship, and the obligations that came with them.

Life and Career

Sukenobu was born in 1762, in the twelfth year of the Hōreki era (宝暦, a Japanese era name used from 1751 to 1764). The Edo period into which he was born had been running since 1603, when Tokugawa Ieyasu established the shogunate at Edo. By the 1760s the country had been at peace under Tokugawa rule for more than a century and a half, and the role of a daimyō had settled into a routine of domain administration, attendance at the shogunal court, and management of a hereditary household.

He became the third lord of Kakegawa Domain and the seventh head of the Kakegawa-Ōta clan. The two counts differ because the clan line predates the domain: the family held its chieftainship across more generations than it had ruled Kakegawa as a domain. Kakegawa sits in Tōtōmi Province, on the road between Edo and the Kansai region, a position that gave the domain strategic weight out of proportion to its size.

Sukenobu died on November 24, 1808, at the age of forty-six by the Western count. His life thus spanned almost exactly the second half of the eighteenth century and the first decade of the nineteenth — a stretch of the Edo period in which the shogunate's finances were under strain, domain lords were pressed to reform their administrations, and the wider Tokugawa order still held firm.

Why They Matter

Sukenobu belongs to the long middle of Edo-period history, the stretch between the founding of the shogunate in 1603 and its collapse in 1868. He is not a figure of national drama. His importance is structural: he is one of the roughly three hundred daimyō whose domains, taken together, were the Tokugawa political system. The shogunate governed through lords like him rather than around them.

As third lord of Kakegawa, he represents the mechanics of hereditary rule in its mature form. A domain passed down a single line; the clan chieftainship passed down the same line; the two were counted separately and inherited together. Sukenobu's tenure shows how that machinery worked in practice across the eighteenth century — a system stable enough that a man could be born into it, inherit it, administer it, and die within it without the structure itself ever being in question.

His position on the Tōtōmi road also ties him to the infrastructure of Tokugawa control. Domains along the great highways were not merely agricultural estates; they were stations in a network that moved lords, officials, and goods between Edo and the imperial capital region. A lord of Kakegawa sat on that network.

The Name in Japanese

The full name is written 太田資順. It is read in kana as おおた すけのぶ, and rendered in romaji as Ōta Sukenobu. The surname comes first, as is standard in Japanese; the given name follows.

The surname 太田 breaks into two kanji:

• 太 — read here as ō. It means "thick," "fat," or "great." In this surname it carries the sense of something large or ample.
• 田 — read here as ta. It means "rice field" or "paddy." It is one of the most common elements in Japanese surnames, a direct trace of a land-based warrior society.

Together 太田 is a classic place-derived surname: a name taken from a locality, in this case one associated with broad rice fields. The long ō in Ōta reflects the reading of 太 as ō rather than ta or futo.

The given name 資順 breaks into two kanji as well:

• 資 — read here as suke. It means "resources," "capital," or "funds," and by extension "endowment" or "qualification." In Edo-period warrior names, 資 was a common element in the suke position, the second syllable of a two-kanji given name.
• 順 — read here as nobu. It means "order," "sequence," "obedience," or "compliance." It appears frequently in samurai given names of the period.

The reading Sukenobu is a nanori reading — a name-specific pronunciation that cannot be predicted from the kanji alone. Both 資 and 順 have other possible readings, and the combination suke + nobu is a convention of warrior naming rather than a phonetic rule. This is why the kana reading おおた すけのぶ matters: it is the only reliable guide to how the name is actually spoken.

Legacy

Sukenobu's legacy is the Kakegawa-Ōta line itself. He was its seventh chieftain and its third lord of Kakegawa Domain, and the house continued after him. In a system built on inheritance, a lord's most durable act was the survival and transmission of his line, and Sukenobu's place in that chain is his historical footprint.

He died on November 24, 1808, and the domain and clan headship passed on. Sixty years later the Edo period ended, and with it the daimyō system that had defined his entire world. The Kakegawa-Ōta name survives in the historical record as one of the houses that administered Tokugawa Japan — not through conquest or crisis, but through the ordinary, continuous work of governing a domain across generations.
