[8][9] Both the Kojiki, and the Nihon Shoki (collectively known as the Kiki) recorded events that took place during Ingyō's alleged lifetime.

[4][6] After more than two years had passed, Oasazuma was finally persuaded by his favorite concubine Oshisaka no Ōnakatsuhime to accept the throne.

[4][6] He learned that the woman's name was "Otohime" ("youngest princess"), but was given the designation of "Sotohori Iratsume" ("clothing pass maiden"[b]) by local men for her beauty.

[4] This was unknowingly a controversial choice as Kinashi was later accused of an incestuous relationship with his sister, Princess Karu no Ōiratsume.

[11] Ingyō couldn't punish his son due to the title he had bestowed upon him, so instead chose an indirect approach by banishing his daughter Karu no Ōiratsume to Iyo.

[4] When Emperor Ingyō died sometime in 453 AD, the king of Silla grieved so much that he presented Japan with 80 musicians to comfort Ingyo's soul.

[13] Scholar Francis Brinkley lists Emperor Ingyō under "Protohistoric sovereigns" whose reign was occupied by an affair and scandal by his son.

[15] His name might have been regularized centuries after the lifetime ascribed to Ingyō, possibly during the time in which legends about the origins of the imperial dynasty were compiled as the chronicles known today as the Kojiki.

Historically women have always been more lightly punished than men for the same offense, and "the particular character of the fault in this case makes such a discrimination all the more reasonable".

[4] Francis Brinkley comments that four facts present themselves during Emperor Ingyō's reign: "Men wore wristbands and garters to which grelots were attached, that a high value was set for pearls, that metal was used for the construction of great man's gates, and the first earthquake is said to have been experienced in 416 AD".

[20] Modern sources have since questioned the reliability of this "first earthquake", opting instead to recognize another that took place in Nara prefecture on May 28, 599 during the reign of Empress Suiko.

[20] While the actual site of Ingyō's grave is not known, this regent is traditionally venerated at a memorial Shinto shrine in Fujiidera Osaka.

Unless otherwise noted (as BC), years are in CE / AD  * Imperial Consort and Regent Empress Jingū is not traditionally listed.
