Champion Carnival
From 1959 to 1972, the Japan Pro Wrestling Alliance (JWA), run by Rikidōzan, held a tournament called World League (also known as the "World Big League"), which featured both Japanese and foreign professional wrestlers. Rikidōzan himself dominated the annual tournament early on, however, after his death in 1963, the tournament was won six times by Giant Baba and once by Antonio Inoki. JWA folded shortly after both Baba and Inoki left the promotion to create All Japan Pro Wrestling (AJPW) and New Japan Pro-Wrestling (NJPW), respectively. Both men took the concept of World League with them to their new promotions, with Baba creating the "Champion Carnival" in 1973 and Inoki creating the World League in 1974, later renaming it G1 Climax.
WAR (wrestling promotion)
On July 28, 1995, WAR was renamed "Wrestle Association R" at a show held in the Korakuen Hall. In 1998, WAR cancelled contracts to the roster and began running less and less cards due to Tenryu's comeback in New Japan, and in July 2000, it promoted a farewell show that served as the prelude to Tenryu's return to All Japan Pro Wrestling (a lot of the wrestlers from WAR also joined AJPW to fill the void by those who joined Mitsuharu Misawa in forming Pro Wrestling Noah). The WAR name was kept for the use of a stable led by Tenryu during brief angles in All Japan and FMW in 2001.
