Emperor Keitai

Keitai (c. 450–531), the 26th emperor of Japan, reigned from 507. Before his accession he ruled in Echizen as Prince Ōdo, a fifth-generation descendant of Emperor Ōjin. When Emperor Buretsu died without an heir in 506, the minister Ōtomo no Kanamura secured the distant kinsman's elevation, and Keitai married Buretsu's sister.

His title long disputed, he entered the Yamato heartland only around 526. In 527 the Iwai Rebellion erupted in Kyushu; he sent Mononobe no Arakabi, who suppressed it. Three of his sons reigned in turn: Ankan, Senka and Kinmei.
