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.
Dynamite Kid
After doing big business in Canada, Dynamite was booked on his first tour of Japan, working for International Pro Wrestling from 19–25 July 1979. Stu Hart and Stampede Wrestling switched their business relationship from IPW to New Japan Pro Wrestling shortly after Dynamite's first tour, and he wrestled for New Japan from 4 January 1980 to 2 August 1984. Perhaps the most memorable matches that came out of Dynamite's run in New Japan were from his now legendary feud against Tiger Mask; Tiger Mask's debut was against Dynamite, in which Tiger Mask shocked the wrestling world by gaining the victory over Dynamite. The two would compete against one another several more times in a feud that is often credited as putting Junior Heavyweight wrestling on the map, as well as setting the standard for future generations. Both the NWA and WWF Junior Heavyweight titles were vacated after Tiger Mask was injured by Dynamite Kid in a tag match on 1 April 1983. Dynamite and Kuniaki Kobayashi competed for the vacant titles, but no winner was decided. On 21 April 1983, Dynamite and Tiger Mask met for the vacant WWF Junior Heavyweight Championship, but no winner was decided after the match ended up as a draw three consecutive times.
