The original World Junior Heavyweight Championship belt had a similar design to the title it replaced, the
NWA International Junior Heavyweight Championship, which had been around since 1982 and only replacing the word "International" with "World". This belt was replaced with a new belt on August 27, 2017. On June 3, 2019, then-champion
Atsushi Aoki died in a motorcycle accident and the belt was retired and given to Aoki's family. A new belt with a new design debuted on January 3, 2020. There have been a total of 47 recognized champions who have had a combined 73 official reigns and six
vacancies. The title is currently held by
Seigo Tachibana who is in his first reign. ==Combined reigns==
