Emperor Yūryaku
A year before his death, Emperor Yūryaku named his third son, Prince Shiraka, his successor, purportedly due to his white hair which gave him his name ("shiraka" = white hair) and which seemed significant to the Emperor. The crown prince was a son with one of the Emperor's concubines , who belonged to the Katsuragi branch of the influential Takenouchi clan. Shortly after the Emperor's death on the 7th day of the 8th month, 479, and before his final burial on the 9th day of the 10th month, 480, another of his consorts, convinced her younger son (who was older than Prince Shiraka), Prince Hoshikawa, to assert his claim to the throne. Wakahime had been the wife of the high official, Tasa, omi of Kibi, but had been captured in a plot by Yūryaku in 463, giving rise to the Kibi Clan Rebellion.
