Naitō Ienaga

Who They Were

Naitō Ienaga (内藤家長, ないとう いえなが) was a Japanese samurai who lived from 1546 to 8 September 1600, spanning the closing decades of the Sengoku period — the "Warring States" era of near-constant civil war — and the brief Azuchi-Momoyama period that followed. He served the Tokugawa clan, the house that would soon unify Japan under a single military government.

Ienaga was the son of Naitō Kiyonaga. He held the rank of daimyo (大名, だいみょう), a territorial lord who governed land and commanded warriors in his own right, and he was famed above all for his skill with the bow. His life ended at Fushimi Castle, one of the opening engagements of the campaign that decided who would rule Japan.

Life and Career

Ienaga entered the service of Tokugawa Ieyasu at a young age. His archery made his name, and he put that reputation to work in Mikawa Province, the Tokugawa heartland, during the suppression of the Ikkō-ikki — armed uprisings of militant Buddhist leagues that resisted samurai rule. His conduct in that fighting earned him Ieyasu's trust, the currency that mattered most in a retainer's career.

In 1590, after Toyotomi Hideyoshi's conquest of the Kantō region, Ieyasu was transferred east to govern it. The move reshuffled the Tokugawa retainer band, and Ienaga received the fief of Sanuki in Kazusa Province, assessed at 20,000 koku. A koku (石, こく) was the quantity of rice reckoned to feed one person for a year, so the figure measured both wealth and the number of troops a lord could field. Twenty thousand koku placed Ienaga among the substantial Tokugawa landholders.

In 1600, as tensions between Tokugawa Ieyasu and Ishida Mitsunari moved toward open war, Ienaga was assigned to the defence of Fushimi Castle alongside Torii Mototada and Matsudaira Ietada. The castle was a deliberate tripwire: holding it would slow any western advance and buy Ieyasu time. Ishida Mitsunari's forces assaulted it, and the garrison was overwhelmed. Ienaga is believed to have been among the last of the castle's defenders killed, on 8 September 1600.

Why They Matter

Fushimi Castle was a sacrifice, and Ienaga was one of the men who paid for it. The garrison's stand delayed Ishida Mitsunari's army long enough for Tokugawa Ieyasu to move his forces west, and the two sides met at Sekigahara in October 1600 — the battle that effectively decided the country's future and cleared the way for the Tokugawa shogunate.

Ienaga's death therefore belongs to the chain of events that opened the Tokugawa century. He did not live to see the victory his stand helped make possible. What he left behind was a son, Naitō Masanaga, who succeeded him and went on to serve in the Osaka Campaign of 1615, the final destruction of the Toyotomi holdouts. The Naitō name continued in Tokugawa service across the generations that followed.

The Name in Japanese

The name is written 内藤家長 and read ないとう いえなが (Naitō Ienaga). It breaks into a family name of two characters and a given name of two characters.

内藤 (ないとう, Naitō) — the surname.

• 内 — read here as ない (nai). It means "inside" or "within". In this compound it carries the sense of the interior or the household.
• 藤 — read here as とう (tō). It means "wisteria". This character is the giveaway in a large family of old surnames: 藤 appears in names such as Fujiwara, Itō, Gotō, Katō and Sudō, many of which trace a connection, real or claimed, to the great Fujiwara lineage. A samurai house bearing 藤 in its name was signalling standing.

家長 (いえなが, Ienaga) — the given name.

• 家 — read here as いえ (ie). It means "house", "home" or "family line". For a warrior, 家 meant the hereditary house itself: its name, its lands, its retainers and its dead. The same character appears in the name of Tokugawa Ieyasu (徳川家康), whose 家 is the identical element.
• 長 — read here as なが (naga). It means "long" or "chief", and in names it often carries the sense of length, seniority or leadership. It is a common closing element in samurai given names of the period.

Put together, 家長 can be read as "the house endures" or "long-lived house" — an auspicious construction of exactly the kind favoured for the sons of warrior families. Note that the surname 内藤 and the given name 家長 use different readings of the same characters in other contexts: 内 is commonly うち, 藤 is commonly ふじ, 家 is commonly か or け, and 長 is commonly ちょう. Only the combination fixes the readings ないとう and いえなが.

Legacy

Ienaga's legacy rests on two things: a bow, and a castle he did not leave. His marksmanship brought him from the ranks of Tokugawa retainers to a 20,000-koku fief, and his death at Fushimi in September 1600 placed him among the defenders whose stand shaped the campaign that followed.

His line continued through his son Naitō Masanaga, who inherited the house and fought at Osaka in 1615. Through Masanaga, and through Ienaga's daughters — one married into the Akamatsu clan, another to Masaki Yoshikatsu — the family's connections reached further into the warrior networks of early Tokugawa Japan. For a retainer remembered chiefly for one skill and one death, that was a durable inheritance.
