Emperor Ichijō
Although Yoritada's two daughters were consorts of Emperor En'yū and Emperor Kazan, they did not have any sons. Yoritada thus had only a tenable blood relationship with the Emperors. His cousin Kaneie was the grandfather of Crown Prince Yasuhito (Emperor Ichijō), and he encouraged Emperor Kazan to abdicate a throne. By the accession of Emperor Ichijō, Yoritada retired from his post as Kampaku, and Kaneie became Sessho (regent) for his grandson Emperor Ichijō. Yoritada was Daijō Daijin from 978, and he is referred to as Rengi-kō (廉義公) (posthumous name of Daijō Daijin).
