Okubo Tadakazu


Tadakazu was a son of Okubo Tadahiro. He served Matsudaira Hirotada and Tokugawa Ieyasu and was active in the latter's struggles against the monto of Mikawa after 1561. While the young Ieyasu was a hostage of the Imagawa, Tadakazu worked effectively to help keep his clan together in his absence.
