Yoshiaki Yatsu
In August 1984, Riki Choshu had formed Ishin Gundan with Animal Hamaguchi, Isamu Teranishi, Yoshiaki Yatsu, Masa Saito and Kuniaki Kobayashi to feud with Antonio Inoki and New Japan Pro-Wrestling. However, just as the feud was heating up, tensions both in and out of the ring forced Ishingun and a few others to leave NJPW that September. The next month, they formed Japan Pro-Wrestling and also announced a co-promotion with All Japan Pro Wrestling. Masa Saito briefly went back to North America but returned to Japan in 1985 and joined in the new promotion.
