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.
Masa Saito briefly went back to North America but returned to Japan in 1985 and joined in the new promotion.
By the end of March 1987, Japan Pro-Wrestling dissolved, as some went back to NJPW, while some stayed with AJPW.
In 2003, Choshu reformed Japan Pro-Wrestling in Fighting World of Japan Pro Wrestling, but after a year, due to financial issues with Kensuke Sasaki, evolved the promotion to Riki Pro and ran smaller scale shows, until Chōshu finally returned to NJPW in 2005 as booker.
Tag Team and Stables Kensuke Sasaki, Koki Kitahara and Super Strong Machine briefly returned to AJPW as freelancers in the mid-2000s.
