For this particular sovereign, the Kojiki and Nihon Shoki tell different versions of what allegedly happened in regard to Emperor Ankō's older brother Prince Kinashi no Karu.

[10][11] Prince Anaho (穴穂) responded with a force of his own which prompted Karu to flee and take refuge at a noble family's residence.

In the Nihon Shoki's version of events, Kinashi no Karu takes his final stand at the residence where he commits an honorary suicide.

[10] The Nihon Shoki does not say what happened to Princess Karu no Ōiratsume other than her being banished to Iyo by Emperor Ingyō during his lifetime for incest.

[10] Ankō believed Ne-no-omi's words and infuriated with rage sent his soldiers to kill Ookusaka and take his wife Nakashi (Emperor Richū’s daughter) as his Kogo.

[10] Sometime in the Autumn of 456 AD, Emperor Ankō confided to Nakashi that he was worried one day Mayowa may seek to avenge his father's death.

[14] Scholar Francis Brinkley lists Emperor Ankō under "Protohistoric sovereigns" whose reign was "a discreditable page of Japanese History".

[15] This would have been a king of Japan (referred to as Wa by contemporary Chinese scholars) who is said to have sent tribute to the Southern Dynasty of China in 462, during the reign of Emperor Taiwu of the Northern Wei.

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

Scholar William George Aston notes in his translation of the Nihon Shoki that Hatahihime and Prince Ookusaka (大草香皇子) are implied in the Shukai as grandchildren rather than children of Emperor Nintoku.

Brinkley argues that if Ōhatuse had no issue with killing several of his family members to obtain the throne, then there is no reason why he wouldn't have started with the reigning emperor.

[13] While the actual site of Ankō's grave is not known, this regent is traditionally venerated at a memorial Shinto shrine at the ruins of Horai Castle in Nara City.
