According to the Kojiki and Nihon Shoki, Buretsu died without a successor, at which time a fifth generation grandson of Emperor Ōjin, Keitai, came and ascended the throne.

[6] According to the Kojiki and Nihon Shoki, his father was Hikoushi no Ō/Hikoushi no Ōkimi (彦主人王) and his mother was Furihime (振媛).

His mother, Furihime, was a seventh generation descendant of Emperor Suinin by his son, Prince Iwatsukuwake.

His father was a fourth generation descendant of Emperor Ōjin by his son, Prince Wakanuke no Futamata.

Although genealogical information in the Shaku Nihongi leaves room for discussion, many scholars acknowledge the blood relationship with the Okinaga clan, a powerful local ruling family or the collateral line of the Imperial family-governed Ōmi region (a part of present-day Shiga Prefecture).

[7] Keitai declared his ascension in Kuzuha, in the northern part of Kawachi Province (present day Hirakata, Osaka), and married a younger sister of Emperor Buretsu, Princess Tashiraka.

It is supposed that his succession was not welcomed by everyone, and it took about 20 years for Keitai to enter Yamato Province, near Kawachi and the political center of Japan at the time.

[1] He is traditionally venerated at a memorial Shinto shrine (misasagi) at the Ooda Chausuyama kofun in Ibaraki, Osaka.
