All Japan Pro Wrestling (AJPW/AJP) or simply All Japan is a Japanese professional wrestling promotion established on October 21, 1972, when Giant Baba split away from the Japanese Wrestling Association and created his own promotion. Many wrestlers had left with Baba, with many more joining the following year when JWA folded. From the mid-1970s, All Japan was firmly established as the largest promotion in Japan. As the 1990s began, aging stars gave way to a younger generation including Mitsuharu Misawa, "Dr. Death" Steve Williams, Kenta Kobashi, Gary Albright, Toshiaki Kawada, Mike Barton, Akira Taue and Jun Akiyama, leading to perhaps AJPW's most profitable period in the 1990s.
