Minamoto no Yorikuni

Minamoto no Yorikuni (died 1058) was a mid-Heian warrior and court official, eldest son of Yorimitsu. He made his career as a middle-ranking officer in the capital, long serving Michinaga's daughter Shōshi.

More man of letters than soldier, he attended Michinaga's Chinese poetry gathering in 1007 and married his daughters to high nobles including the regent Fujiwara no Morozane. His real deeds were police work, like arresting an assailant in 1019, though legend sends him with his father against Shuten-dōji.
