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.
Wrestling World 2003
Wrestling World 2003 was a professional wrestling event held by New Japan Pro-Wrestling (NJPW). The event took place on January 4 in the Tokyo Dome. Wrestling World 2003 was the twelfth January 4 Tokyo Dome Show promoted by NJPW. The show drew 30,000 spectators. The show featured the semi-finals and the finals of the "Young Generation Cup", an NJPW tournament for relative newcomers who have yet to establish themselves as top level wrestlers, which saw Ryushi Yanagisawa defeat Yutaka Yoshie to win the cup. The show featured a total of eleven matches, including a match for the vacant NWF Heavyweight Championship that Yoshihiro Takayama won by defeating Tsuyoshi Kosaka in the finals of a four-man tournament. The main event was a successful defense of the IWGP Heavyweight Championship as champion Yuji Nagata defeated Josh Barnett.
