Tokiwa Gozen

Tokiwa Gozen (常盤御前), or Lady Tokiwa, was a Japanese noblewoman of the late Heian period and mother of the great samurai general Minamoto no Yoshitsune. Sources disagree as to whether she was a concubine or wife to Minamoto no Yoshitomo, of which she bore Minamoto no Yoshitsune. She was later captured by Taira no Kiyomori, but escaped.
