IWRG was affiliated with Último Dragón and Toryumon Mexico (Ultimo Dragon Gym) from the time of IWRG's creation until 2001. The early Toryumon Mexico shows were co-promoted by IWRG and Último Dragón in Naucalpan and students regularly worked on IWRG s shows. CIMA, SUWA, Yasushi Kanda, Susumu Mochizuki and Magnum Tokyo have all held IWRG championships through the working relationship.
