Heisei Ishingun
Upon leaving his stint in WWF, Shinzaki returned to Japan. He made a single night appearance with New Japan Pro-Wrestling at "Battle Formation" on April 29, 1996, where he wrestled The Great Muta. Shinzaki was introduced as a mystic, supernatural character very much like Muta, who embodied evil while Shinzaki embodied good. Shinzaki was defeated in a spirited brawl. One year later on January 4's "Wrestling World In Tokyo Dome 1997", he faced and defeated Heisei Ishingun member Michiyoshi Ohara, who had a similar gimmick to his, and mimicked everything Shinzaki did.
