In August 1180, Shigenaga attacked Muira Yoshizumi, an ally of the rival Minamoto clan.
In return, Yoritomo granted Shigenaga seven new estates in Musashi Province, including Kitami in what is now Tokyo's western Setagaya Ward.
In 1593, in a pledge of obedience to Tokugawa Ieyasu, Edo Katsutada changed the clan name to Kitami.
Katsutada was employed by the first and second Tokugawa shōguns, reaching the position of Magistrate of Sakai, south of Osaka.
Katsutada's grandson-in-law, Shigemasa, found favor with the fifth shōgun Tokugawa Tsunayoshi.
Tombstones of several generations of the clan are at Keigen-ji, a Buddhist temple founded in 1186 by Edo Shigenaga, in Kitami.
