The Takeda are descendants of Emperor Seiwa (858–876), the 56th Emperor of Japan, and are a branch of the Minamoto clan (Seiwa Genji), by Minamoto no Yoshimitsu (1056–1127), son of the "Chinjufu-shōgun" Minamoto no Yoriyoshi (988-1075), and brother to the famous Minamoto no Yoshiie (1039–1106). Minamoto no Yoshikiyo (1075–1149), son of Yoshimitsu, was the first to take the name of Takeda.
