Tango Province
This clan's origin is a descendant of Mononobe clan. Mononobe clan are descended directly from god of Nigihayahi-no-mikoto (Legend age) by his descendant Mononobe no Arakabi (Kofun period), Takaoka Sadamochi, descendant of Mononobe no Arakahi, is the first who took the name of Takaoka. Sadamochi's 8th grandson Takaoka Sadami became Ashikaga Takauji's subordinate and there were distinguished military services. And, because he had received the territory(Itanami-sho, Yosa-gun, Tango Province), the clan moved there. There are a lot of descendants of him about the place now.
