Emperor Sanjō

Emperor Sanjō (976–1017), personal name Okisada, was the second son of Emperor Reizei and the sixty-seventh sovereign of Japan. Named crown prince in 986, he only took the throne in 1011, and his relations with Fujiwara no Michinaga soon grew strained.

Having lost his sight, Sanjō abdicated in 1016 on condition that his eldest son Atsuakira become crown prince. He took Buddhist vows in 1017 and died months later; that year Atsuakira withdrew from the succession under Michinaga's pressure.
