Ō no Yasumaro

Who They Were

Ō no Yasumaro (太安万侶, おおの やすまろ) was a Japanese nobleman, bureaucrat and chronicler of the Nara period (710–794), the era when Japan's first permanent capital was established and the young state began writing down its own past. He is remembered for one achievement above all others: compiling and editing the Kojiki (古事記), the oldest surviving Japanese history. He died on 15 August 723, in the seventh year of the Yōrō era (養老), in Nara.

His family, the Ō, belonged to the hereditary nobility that staffed the Yamato court. Yasumaro worked as a historian and writer under Empress Genmei (r. 707–721), the monarch who commissioned the Kojiki. In a court where literacy, ritual knowledge and genealogy were instruments of political power, that combination of rank and scholarship placed him at the centre of one of the most consequential literary projects in Japanese history.

Life and Career

Yasumaro may have been the son of Ō no Honji, a participant in the Jinshin War of 672 — a violent succession dispute that reshaped the Yamato court and the aristocratic families tied to it. If the connection is correct, Yasumaro inherited a family position close to the throne, and a family memory of the court's most turbulent years.

In 711, Empress Genmei charged him with the duty of writing the Kojiki, working from the differing chronicles kept by the great clans and from native myths. The empress's instruction was political as much as literary: Japan had recently adopted a Chinese-style legal code and a Chinese-style capital, and an official account of the origins of the imperial line and the leading families served the state's need for a single authorised past.

Yasumaro did not work alone. He was assisted by Hieda no Are (稗田阿礼), a court figure who possessed a prodigious memory for the old genealogies and legends. The Kojiki was finished the following year and presented to Empress Genmei in three volumes in 712. Yasumaro's role was that of compiler and editor: he set down, ordered and shaped material that had circulated orally and in clan records, and he wrote the preface that explains how the work came to be made. He died in Nara on 15 August 723, in the seventh year of Yōrō.

Why They Matter

The Kojiki is the oldest extant Japanese history, and Yasumaro is the person who made it a book. Without his compilation, the myths of the gods, the genealogies of the imperial house and the traditions of the leading clans would survive, if at all, only in scattered and later sources.

The work is also a landmark in the Japanese language. It was written largely in Chinese characters used for their sounds as well as their meanings, an early attempt to record Japanese speech with a script designed for Chinese. That makes it a founding document for anyone interested in how Japanese came to be written at all.

Yasumaro's position at court gave the project its authority. A nobleman and bureaucrat compiling on the orders of a reigning empress produced a text with official standing — not a private antiquarian collection but a state-sanctioned account of origins, presented to the throne in 712.

The Name in Japanese

The full name is written 太安万侶. In kana it is おおの やすまろ, and in romaji it is Ō no Yasumaro. The name has three elements: the family name 太 (Ō), the particle の, and the given name 安万侶 (Yasumaro).

太 — read Ō here. The character means "great", "thick" or "fat". As a surname it is written with a single character, and the long ō is a long vowel, held roughly twice as long as a short o. The family is often referred to as the Ō clan.

の — the particle no, written in kana rather than kanji. It links the family name to the given name, roughly the way "of" works in English names. In modern Japanese, family names and given names are usually written without it, but in older names and historical texts it appears frequently.

安 — read yasu. The character means "peace", "calm" or "safe". It is a common element in Japanese personal names, and it appears in the name of the era's capital, Heijō-kyō, and in many later names.

万 — read ma. The character means "ten thousand" or, by extension, "myriad" or "countless". It is one of the most recognisable numerals in Japanese, and it also carries the sense of "all" or "everything" in literary use.

侶 — read ro. The character means "companion", "fellow" or "partner". It is the final element of the given name, and it is the rarest of the three characters in ordinary modern Japanese.

Read together, 安万侶 (Yasumaro) is a name built from auspicious and expansive elements: peace, ten thousand, and companionship. The name is a useful reminder that Japanese personal names are usually read by convention rather than by the individual characters' most common pronunciations — the same characters can carry quite different readings in other names.

Legacy

The Kojiki survives as the foundation text of Japanese myth, history and early language study. Its three volumes, presented to Empress Genmei in 712, preserve the accounts of the gods, the origins of the imperial line and the traditions of the clans that Yasumaro assembled on the empress's orders.

Yasumaro's reputation rests on that single act of compilation. He is remembered as the editor who turned a body of oral tradition and clan record into a written work of state, and as the author of its preface, which describes the making of the book. His death in Nara on 15 August 723, in the seventh year of Yōrō, closes the record of a career spent in service to the court and its memory.
