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.
All Asia Tag Team Championship
The (All) Asia Tag Team Championship is a professional wrestling tag team title in Japanese promotion All Japan Pro Wrestling (AJPW). It was created on November 16, 1955, in the Japan Wrestling Association (JWA) when King Kong Czaya and Tiger Joginder Singh defeated JWA founder Rikidōzan and Harold Sakata in a tournament final. It was abandoned in 1973 when the JWA closed, but was later revived in 1976 by AJPW in response to New Japan Pro-Wrestling (NJPW) announcing the creation of its own version of the title. It is currently one of two tag team titles in AJPW, along with the World Tag Team Championship. It is also the oldest active title in Japan. There have been a total 105 official reigns, as the first 27 reigns from the JWA is also recognized by AJPW.
