Yamagata Masakage

Who They Were

Yamagata Masakage (山県昌景, やまがた まさかげ) was a samurai general who served the Takeda house during the Sengoku period, the century and a half of near-constant civil war that tore Japan apart between the collapse of central authority and the country's reunification. He was born in 1524, in the fourth year of the Daiei era (大永, だいえい), and died on 29 June 1575. His life therefore spans almost exactly the period in which the Takeda clan of Kai province rose from a regional power to one of the most feared military machines in Japan.

He is remembered above all as one of the "Twenty-Four Generals of Takeda Shingen" (武田信玄の二十四将), a group of senior commanders traditionally listed as the finest officers in the Takeda army. He was also a personal friend of Takeda Shingen himself, an unusual distinction for a retainer in a hierarchy built on absolute obedience.

Life and Career

Masakage was born into the Obu family. His father was Obu Dōetsu (飯富道悦), and his elder brother was Obu Toramasa (飯富虎昌), a senior Takeda retainer who commanded the famous "red fire unit" — a formation whose soldiers wore red armour, derived from Shingen's slogan Fūrinkazan (風林火山), the four-phrase motto borrowed from Sun Tzu's Art of War. At some point Masakage took the surname Yamagata rather than Obu, and he is also recorded under the name Obu Masakage.

He became a general in the Takeda military structure, and his reputation rested on two things: battlefield skill and his own red armour. The red colour was not decoration. It marked the unit out on a chaotic battlefield, made its commander instantly identifiable to his own men, and signalled to the enemy exactly who was coming. Masakage inherited and continued the tradition his brother had established.

His recorded career ends at the Siege of Kannomine (神之峰城の戦い). He died on 29 June 1575. That date places his death in the same year as the Battle of Nagashino, the engagement in which the Takeda cavalry charge was broken by massed arquebus fire — a battle that permanently changed how Japanese armies fought. Masakage did not live to see the Takeda clan's final destruction, which came in 1582.

He left four recorded sons: Yamagata Masashige (山縣昌重), Yamagata Masahisa (山縣昌久), Yamagata Nobutsugu (山縣信次), and Yamagata Masamitsu (山縣昌光). The Yamagata name continued through them.

Why They Matter

The Twenty-Four Generals were the instrument through which Takeda Shingen controlled and expanded his territory, and Masakage stood near the top of that group. His importance is not merely that he fought well. It is that he represents a specific moment in Japanese military history: the age of the professional, career-long retainer-general, a man whose entire adult life was one institution, one lord, and one army.

That world ended within a decade of his death. The Takeda house was extinguished in 1582, and the samurai who survived the Sengoku period were reorganised into the peacetime bureaucracy of the Tokugawa shogunate. Masakage belongs to the last generation of samurai who spent their whole lives in actual warfare.

His red armour also matters culturally. The image of the red-armoured Takeda warrior is one of the most recognisable visual motifs in Japanese historical fiction, film, and video games, and Masakage is one of the men that image is built on.

The Name in Japanese

The full name is written 山県昌景. It is read やまがた まさかげ in kana, and romanised as Yamagata Masakage. Japanese personal names are written surname first, so 山県 is the family name and 昌景 is the given name.

山 — read やま (yama) here. It means "mountain". It is one of the most common elements in Japanese place names and surnames.

県 — read がた (gata) here. On its own the character normally means "prefecture", the administrative unit used in modern Japan. In this surname it is a phonetic and orthographic element rather than a reference to a prefecture; the surname 山県 predates the modern prefecture system by centuries. Note the sound change: やま + かた becomes やまがた, with the k voicing to g — a standard Japanese compounding effect called rendaku (連濁, れんだく).

昌 — read まさ (masa) here. It means "prosperous", "flourishing", or "bright". It is an extremely common element in samurai given names of this period, and Takeda Shingen's own name, Harunobu (晴信), uses a different but similarly auspicious character.

景 — read かげ (kage) here. It means "scenery", "view", or "light". Combined with 昌, the given name 昌景 carries a sense of brightness and clear sight.

One further point of interest: the character 県 in 山県 is a simplification of an older form. The surname is sometimes written 山縣, using the unsimplified character, and both spellings refer to the same family.

Legacy

Masakage's legacy is bound up with the Takeda war machine and its most famous visual signature. The red armour of the Takeda vanguard, the Fūrinkazan banner, and the roster of the Twenty-Four Generals are the three images through which the Takeda clan is remembered, and Masakage is attached to all three.

He is also remembered through his family line. His four sons carried the Yamagata name forward, and the surname survives in Japan today. For students of Japanese, the name is a useful study case: it contains rendaku in action, a kanji whose everyday meaning ("prefecture") is not its meaning in the name, and two given-name characters that recur constantly across Sengoku-period figures.
