Ōgimachisanjō

The Ōgimachisanjō were a Kyoto court-noble house, a branch of the Sanjō family of the Northern Fujiwara Kan'in line. Its founder Kin'uji was a son of Sanjō Sanefusa; his mansion fronted Ōgimachi-Tōin street, giving the line its name.

The house rose under Kinhide, whose daughter Hideko entered Emperor Kōgon's harem and bore Emperors Sukō and Go-Kōgon. Kinhide and his next two heirs reached the Inner Minister's post, settling the family's minister-house standing. Kinhide and his father Sanemi kept diaries of the late Kamakura and Nanboku-chō decades.

The tenth head Sanemasa, whose sister married Shogun Ashikaga Yoshinori, was wounded resisting the assassins who killed him in the Kakitsu Incident of 1441. In the Edo period the house lived on 200 koku and produced no minister; its 23rd head Kinkazu was stripped of office and confined for life in the Hōreki Incident.
