Emperor Go-Reizei

Emperor Go-Reizei (1025–1068), personal name Chikahito, was the 70th emperor of Japan, the eldest son of Emperor Go-Suzaku and Fujiwara no Yoshiko. He succeeded on his father's abdication in 1045 and reigned 23 years, with Fujiwara no Yorimichi and later Norimichi holding the kampaku regency.

In 1051 the Abe clan rose in the north, beginning the Zenkunen War; Minamoto no Yoriyoshi was sent against them and crushed the Abe by 1062. Go-Reizei left no children at his death in 1068, so the throne went to his half-brother, Emperor Go-Sanjō.
