Akitoshi Saito
After an intense feud with each other early from 1988, Shiro Koshinaka and Kuniaki Kobayashi formed a tag team, and feuded with many other teams from 1988 to 1992. Between those rivalries, they feuded with Masashi Aoyagi and Akitoshi Saito who were karate fighters, to prove which sport was the best. After defeating them many times, Kobayashi, Koshinaka, Saito and Aoyagi formed a stable. Kengo Kimura and the Great Kabuki from WAR soon joined the group. In 1993, they were initially called Han-Senshukai Dōmei (Anti-Wrestlers Alliance) referring to WAR and Genichiro Tenryu. After this feud was over, they changed their name to Heisei Ishingun, after Riki Choshu's Shōwa period Ishin Gundan stable.
