The Independent World Junior Heavyweight Championship(Japanese: インディペンデントワールド世界ジュニアヘビー級王座, Hepburn: Indipendento Wārudo Sekai Junia Hebī-kyū Ōza) is a professional wrestling championship that is being defended in various independent promotions in Japan. The title was originally created in 1993 by Frontier Martial-Arts Wrestling.

There have been a total of 41 reigns spread over three lineages and shared among 36 different wrestlers. The current champion is Megaton who is in her first reign.

History

The title was created in 1993 by Frontier Martial-Arts Wrestling (FMW) and it stayed with FMW from its inception to mid-1999, when FMW retired it. In 1998, the title was renamed FMW Junior Heavyweight Championship(FMW認定ジュニアヘビー級王座, FMW-nintei Junia Hebī-kyū Ōza) with the launch of the FMW Unified Organization. It was considered a different title with a new lineage.

On May 31, 1999, Kodo Fuyuki became the FMW commissioner and withdrew the recognition of the title following the introduction of the WEW Single Championship which he awarded to himself on September 24. Yuhi Sano was then recognized as the first Independent World Junior Heavyweight Champion, in continuation of his FMW Junior Heavyweight Championship reign, thus starting a third lineage. Since then, the title has been defended in various Japanese promotions including Big Japan Wrestling, DDT Pro-Wrestling, Kaientai Dojo, Union Pro Wrestling, Osaka Pro Wrestling and Michinoku Pro Wrestling.

Despite FMW no longer recognizing the title, the original championship belt—still bearing the 'FMW' name—continues to be used. In May 2010, a new belt was created when Tarzan Goto's Super FMW promotion briefly revived the FMW Independent World Junior Heavyweight Championship to crown its final champion.
