Osuga Taneuji - Osuga Taneuji

...A powerful clan in Shimousa in the Middle Ages. The Chiba clan of the Taira surname. It began with Tanenobu, the fourth son of Chiba no Suke Tsunetane. Tanenobu served as the vanguard in Minamoto no Yoritomo's conquest of Oshu, and in the rear guard in the battle to eliminate Hatakeyama Shigetada. His descendants were active as one of the Chiba Rokuto, based in Osukaho, Katori County, Shimousa Province (present-day Daiei Town, Katori County, Chiba Prefecture). They also held land in Kamiyago, Koshimasho, Iwaki County, Mutsu. Tanenobu's grandson Taneuji, under orders from the Kamakura shogunate, attacked and defeated Chiba Hidetane, who was implicated in the Battle of Hoji (1247), in Kazusa Ichinomiya. During the Nanboku-cho and Muromachi periods, the Chiba family declined, but they remained active as influential figures in Chiba clan uprisings, serving as deputy shugoshu (military governor), and during the Uesugi Zenshū Rebellion they sided with Zenshū, marching to Kamakura Yonemachi-omote as members of the Chiba clan in October 1416 (Oei 23). During the Battle of Yuki in March 1440 (Eikyo 12), Osuga Echigo-no-kami joined the Yuki side, plotting the revival of the Kanto kubo (Japanese governor of the Kanto region).
