Source-derived summary

Prince Ōtomo (648–672), also known under the posthumous title Emperor Kōbun (弘文天皇), was a Japanese noble who briefly ruled over the imperial court in 672, during the Jinshin War of the late Asuka period. He was born as Prince Iga to Prince Naka no Ōe. Iga changed his name to Ōtomo and married his cousin Princess Tōchi. After several years as regent, Naka ascended to the throne as Emperor Tenji in 668. He appointed either his son Ōtomo or brother Ōama as his heir. He also appointed Ōtomo as the first Daijō-daijin ('prime minister'), overseeing the Daijō-kan ('council of state').

Following Tenji's death in 671, a succession dispute broke out between Ōtomo (residing at court in Ōmi) and Ōama (who had traveled to Yoshino, possibly suspecting a plot against him). Fearing an attack by Ōtomo's forces, Ōama fled and rallied soldiers across the eastern province in mid-672, beginning the Jinshin War. A month later, Ōama's forces routed those of the Ōmi court. Ōtomo is said to have fled to the mountains and committed suicide, although he may have instead been betrayed by his minister Mononobe no Maro.

Editorial summary

Begin with the source’s own compact description: “Prince Ōtomo” is emperor of Japan. The dossier treats that line as a proposition to test through Prince, Ōtomo and Emperor, not as a finished interpretation.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail. The current 187-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 0648. For this dossier, Prince, Ōtomo and Emperor is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “emperor of Japan” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q357242. VIAF identifies the subject as 35998832. The Library of Congress control number is n88062351. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
