Kikuchi clan
Noritaka held a high position in the Daizaifu Government. When Fujiwara no Takaie moved back to Kyoto in 1070 (2nd year of Enkyū) Noritaka decided to retire and built a retirement villa in Kikuchi District (Kikuchi-gun), Higo Province where he lived until his death. The remains of the villa can still be seen today. In 1071 (3rd year of Enkyū) he became master of Kikuchi District where he established a castle town with retainers. Today there is a city in Kumamoto Prefecture called Kikuchi, Kumamoto. He took the name of his district and founded the Kikuchi clan.
