WWA World Junior Light Heavyweight Championship

In the 1990s, the title was taken to Japan when reigning champion Gran Hamada returned to his home country.

When the J-Crown was broken up into individual titles the WWA World Light Heavyweight Championship returned to Mexico.

[b] On occasion the promotion declares a championship vacant, which means there is no champion at that point in time.

This can either be due to a storyline,[c] or real life issues such as a champion suffering an injury being unable to defend the championship,[d] or leaving the company.

The title is used by Zero1 but only shares the name of the World Junior Light Heavyweight Championship, not its lineage.
