Source-derived summary

Iitoyo (飯豊青皇女, 440–485) was a Japanese imperial princess and allegedly empress regnant for a short period between Emperor Seinei and Emperor Kenzō.

Given names

Princess Iitoyo (飯豊青皇女) is also referred to as Queen Iitoyo (飯豊青尊), Oshinumi (青海郎女 or 忍海郎女), and Princess Aomi (飯豊郎女). Her primary name Iitoyo is an old Japanese word for an owl ("いひとよ"), "Oshinumi" is the name of a place in Katsuragi, while the origin of Aomi remains unknown. It's also noted that Iitoyo has also been given the posthumous names: Seitei–tenno and 'Tsunuzashi-tenno. This latter title was more than likely assigned to her by later generations as there is no evidence to suggest that the title tennō (meaning "emperor") was used during the 5th century for Japanese monarchs.

Traditional narrative

The Japanese have traditionally accepted this royal's historical existence, and a mausoleum (misasagi) for Iitoyo is currently maintained. The following information available is taken from the pseudo-historical Kojiki and Nihon Shoki, which are collectively known as Kiki (記紀) or Japanese chronicles. These chronicles include legends and myths, as well as potential historical facts that have since been exaggerated and/or distorted over time. Princess Iitoyo was born sometime in 440 AD and is also referred to as "Aomi no Himemiko" (青海皇女). While both chronicles agree that Iitoyo descended from Emperor Richū, the exact degree of this relationship is told differently.

Editorial summary

Begin with the source’s own compact description: “Princess Iitoyo” is japanese empress regent (440-484). The dossier treats that line as a proposition to test through Princess, Iitoyo and Japanese, not as a finished interpretation.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 223-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The linked authority record independently contributes the date 0380-09-24. For this dossier, Princess, Iitoyo and Japanese is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “japanese empress regent (440-484)” 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 26, 2026. The linked authority identifier is Q545771. 1 of 1 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 lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
