Genealogy
He was the second son of Emperor Kimmei by his consort Iwahime, a daughter of Emperor Senka.
According to the Nihonshoki and Gukanshō, Bidatsu had four empresses and 16 Imperial children (6 sons and 10 daughters).
Bidatsu's first empress, Hirohime, died in the fifth year of his reign. To replace her, he elevated one of his consorts, Princess Nukatabe, to the rank of empress. Nukatabe was his half-sister by their father Kimmei. Later she ascended to the throne in her own right and is today known as Empress Suiko.
Though he had many children, none of them would ever become emperor. He was succeeded first by one of his brothers, Emperor Yōmei, then by another, Emperor Sushun, and then Empress Suiko, his sister and wife, before his grandson, Emperor Jomei, eventually took the throne.
