Tatsumi Fujinami
Choshu was the first "traitor heel" in a Japanese promotion. In 1983, upset at not being selected for the inaugural tournament for the IWGP Heavyweight Championship, he turned on Tatsumi Fujinami during a match and formed his own stable, "Ishin Gundan" (Revolutionary Army), which was the core for the later Japan Pro-Wrestling (JPW) promotion that "invaded" All Japan Pro Wrestling (AJPW).
