Fujiwara no Korechika

Fujiwara no Korechika (藤原 伊周, 974 – February 14, 1010), the second son of Michitaka, was a kugyo (Japanese noble) of the Heian period.

His sister Teishi (Sadako) was married to Emperor Ichijō, and Korechika aspired to become the regent (Sessho) for his young brother-in-law after his father's death.

In Chōtoku 2 (長徳２年) (996), Korechika and his younger brother Takaie were exiled to Dazaifu.

He was pardoned a year later, and subsequently became Jun-Daijin (associate minister; 准大臣).

Korechika is sometimes referred to as Gidō-sanshi (儀同三司) or Sochi no Naidaijin (帥内大臣).
