Emperor Ichijō
, fifth son of Michinaga, was a kugyo of the Heian period. His mother was Minamoto no "Rinshi" (源 倫子), daughter of Minamoto no Masanobu. Regent Yorimichi, Empress "Shōshi" (consort of Emperor Ichijō), Empress "Kenshi" (consort of Emperor Sanjō) were his brother and sisters from the same mother. In 1068, the year when his daughter married Emperor Go-Reizei, he took the position of Kampaku, regent. He, however, lost the power when Emperor Go-Sanjo, who was not a relative of the Fujiwara clan, assumed the throne. This contributed to the later decline of the Fujiwara clan.
