In a legend in Fujisawa-shuku (a posting station which was located in the present Fujisawa City, Kanagawa Prefecture), a family (Kawakami clan) appears which claims as the descent from Nobukuni ODA, the second son of Nobutoyo ODA, who was himself the son of Nobutaka's concubine from the Ozuma clan; this family is still in existence.
