The head of this clan was said to be the nephew of Kageakira ASAKURA, but there are many unclear points about his father's life and so on, and the connection with the Echizen-Asakura clan can not be confirmed (His father could have been a retainer of the Hojo clan, or a member of a certain family line of the Asakura clan of Ise Province or the Asakura clan of Totomi Province.)
朝倉景鏡の甥とされるが、父親の動向等に不明な点が多く、越前朝倉氏との関連は確定ではない（北条家臣、もしくは伊勢、遠江の朝倉氏等の系統か？）。
