In 1996, Satomura started appearing for World Championship Wrestling (WCW) through Gaea Japan's working relationship with WCW which was attempting to establish a women's division. Satomura participated in an eight-woman tournament for the inaugural WCW Women's World Championship but was eliminated in the first round by eventual winner Akira Hokuto. When WCW introduced a second title for the women she entered into that tournament too, but was again knocked out in the first round by Toshie Uematsu who went on to win the tournament. Satomura continued to make appearances for WCW until the business relationship between the two promotions ended.
