Fujiwara no Muchimaro

Who They Were

Fujiwara no Muchimaro (藤原武智麻呂, ふじわら の むちまろ) was a courtier and politician of the late Asuka and early Nara periods, born in 680 and dead on 29 August 737. He was the eldest son of Fujiwara no Fuhito, the man who built the Fujiwara clan into the dominant force at the Japanese court, and of Soga no Shōshi, a daughter of the Soga house. Through his mother he carried the blood of the clan that had run Japanese politics in the generation before his birth; through his father he carried the surname that would run it for centuries after.

Muchimaro reached Senior First Rank, the highest court rank in the ritsuryō system, and held all three of the great ministerial posts: Dainagon (大納言, だいなごん, Great Councillor), Udaijin (右大臣, うだいじん, Minister of the Right) and Sadaijin (左大臣, さだいじん, Minister of the Left). He founded the Nanke (南家, なんけ, "Southern House"), one of the four branches into which the Fujiwara clan divided in the Nara period. He was married to Abe no Sadahime and to a daughter of Ki no Maro, and he had six recorded children: Fujiwara no Toyonari, Fujiwara no Otomaro, Fujiwara no Nakamaro, Fujiwara no Kosemaro, Fujiwara Nanafu, and a daughter known as Minami Dono.

Life and Career

Muchimaro was born in 680, in the twentieth year of the Hakuhō era (白鳳, はくほう), during the Asuka period. His father Fuhito was then a rising minister in the government of the ritsuryō state, the Chinese-style legal and administrative system that was being assembled at the Japanese court through the seventh century. Muchimaro grew up inside that system and was promoted through it.

His career is inseparable from his father's. Fuhito died in 720, leaving four sons — Muchimaro, Fusasaki, Umakai and Maro — who are known collectively as the Fujiwara Four. The four brothers did not scatter their influence; they coordinated it, each taking a leading place at court and each founding a branch of the clan. Muchimaro, as the eldest, took the southern branch, the Nanke.

He rose to Dainagon, then to Udaijin, and finally to Sadaijin, the senior of the two great ministers of state. In the court of Emperor Shōmu, Muchimaro was one of the four men who effectively directed the government.

In 735 a smallpox epidemic broke out in Kyushu and spread across the country. Over the following two years it killed a large share of the Japanese population, and it did not spare the court. Muchimaro died on 29 August 737. Within months, all four of the Fujiwara brothers were dead of the same disease. The deaths of the four removed the clan's entire leading generation at once and opened a bitter struggle for control of the court among the survivors.

Why They Matter

Muchimaro matters for three reasons, and they are connected.

First, he founded the Nanke, the Southern House of the Fujiwara. The Fujiwara clan did not remain a single body; it divided into branches that competed with each other for offices and marriages across the Nara and Heian periods. The Nanke was one of the four, and Muchimaro was its head. His descendants carried the name forward for generations.

Second, he was one of the four Fujiwara brothers who, between them, held the central offices of the Japanese state in the 720s and 730s. Their concentration of power is the moment the Fujiwara stop being one ambitious family among several and become the family at court.

Third, his death is a historical hinge. The smallpox epidemic of 735–737 killed all four brothers within a short span, and the political order they had built collapsed with them. What followed — the rise of Tachibana no Moroe, the plotting of Fujiwara no Hirotsugu, and eventually the career of Muchimaro's own son Nakamaro — is a direct consequence of the vacuum left in 737.

The Name in Japanese

The full name is written 藤原武智麻呂. It is read ふじわら の むちまろ in kana, and romanised as Fujiwara no Muchimaro.

藤 — read fuji here. It is the kanji for "wisteria," the climbing vine. The Fujiwara took their name from the place where the family's ancestor was said to have been buried, near wisteria fields. The same character appears in the surname of every branch of the clan.

原 — read hara here, but voiced to wara inside the compound. It means "plain," "field," or "moor." Together, 藤原 is "wisteria field."

の — the possessive particle, written in kana rather than kanji. In classical names of this kind it links the surname to the personal name, roughly "of the Fujiwara." It is not part of the family name itself.

武 — read mu here. Its usual meanings are "martial," "military," "brave." In this name it is used for its sound, not its sense.

智 — read chi here. It means "wisdom," "intellect," "cleverness."

麻 — read ma here. It means "hemp" or "ramie," the fibre plant. It also appears in the word 麻呂 below.

呂 — read ro here. It is a character used almost exclusively in old male personal names, where it functioned as a suffix. Its literal sense is "spine" or "backbone," but in names it is purely phonetic.

The personal name 武智麻呂, Muchimaro, is therefore a typical Nara-period male name: a string of auspicious or simply pleasant-sounding characters, with 麻呂 as the closing element. Names of this shape — ending in -maro — were standard for men of the period, and Muchimaro's own sons carry the same ending in Toyonari, Otomaro, Nakamaro and Kosemaro.

Legacy

Muchimaro's most direct legacy is the Nanke itself. The branch he founded produced a line of courtiers that remained active in Nara and Heian politics, and it is through the Nanke that his descendants are traced.

His son Fujiwara no Nakamaro became one of the most powerful and most controversial figures of the eighth century, rising to dominate the court of Empress Kōken before his rebellion and death in 764. Another son, Fujiwara no Toyonari, also reached high office and is named in the records as a reference point for his father's line. The family Muchimaro left behind was, within a generation, again at the centre of Japanese politics — the same position it had held when he and his three brothers were alive.

Muchimaro is remembered chiefly as the eldest of the Fujiwara Four and as the founder of the Southern House. His career shows how the Fujiwara operated in their first great generation: not as lone individuals but as a coordinated set of brothers, each holding a great office, each founding a branch, each marrying into another powerful family. The epidemic of 735–737 ended that generation in a single stroke, and the history of the following decades is the story of the men who tried to fill the space the four brothers left.
