# Oz Academy Tag Team Championship

The Oz Academy Tag Team Championship is a professional wrestling tag team championship owned by the Oz Academy professional wrestling promotion. The championship was introduced on July 13, 2008, when Carlos Amano and Dynamite Kansai defeated Chikayo Nagashima and Sonoko Kato in the finals of a tournament to become the inaugural champions.
Like most professional wrestling championships, the title is won as a result of a scripted match. There have been a total of thirty-seven reigns shared among twenty-nine teams and thirty-two wrestlers. Jaguar Yokota and Mayumi Ozaki are the current champions in their first reign as a team, while it's the seventh reign individually for Kato and the first for Ozaki.

## Reigns

Carlos Amano and Dynamite Kansai were the first champions in the title's history. SonChika (Chikayo Nagashima and Sonoko Kato) and Jungle Jack 21 (Hiroyo Matsumoto and Tomoka Nakagawa) share the record for most reigns as a team, with three. The former's second reign holds the record for the shortest reign in the title's history, at 14 days, while the latter's third reign holds the record for the longest reign, at 385 days. Mayumi Ozaki and Sonoko Kato hold the record for most reigns individually, with seven.
