Emperor Reizei

Emperor Reizei (950–1011), personal name Norihira, was Japan's 63rd emperor, reigning from 967 to 969. The second son of Emperor Murakami, he was made crown prince in infancy through the Fujiwara brothers Morosuke and Saneyori.

He grew up mentally ill, so at his accession at eighteen Fujiwara no Saneyori ruled as regent. In 969 the Anna Incident brought down Minamoto no Takaakira, and Reizei abdicated the same year. He lived forty-four years in retirement, dying in 1011; his sons became Emperors Kazan and Sanjō.
