Along with his younger brother, Prince Woke, Oke was raised to greater prominence when Emperor Seinei died without an heir.

Rather, it was presumably Sumeramikoto or Amenoshita Shiroshimesu Ōkimi (治天下大王), meaning "the great king who rules all under heaven".

Ninken married to Emperor Yūryaku's daughter Kasuga no Ōiratsume no Himemiko, a second cousin of him.

There apparently was also another daughter, Princess Tachibana, who in turn is recorded to have become a wife of Senka and mother of Princess Iwahime, who herself became a consort of Kimmei and bore Emperor Bidatsu, a future monarch and lineal ancestor of current monarchs of Japan.
