The Junior Tag League is an annual professional wrestling tag team tournament held by the All Japan Pro Wrestling (AJPW) promotion. The tournament is meant for wrestlers under the weight limit of 100 kg (220 lb), who are referred to in Japan as junior heavyweights. In 2013, the tournament was rebranded Junior Hyper Tag League (ジュニア・ハイパー・タッグ・リーグ, Junia Haipā Taggu Rīgu), following in the footsteps of the Junior League, which had been renamed "Junior Hyper League" the previous year. In 2014, the tournament was again rebranded after the singles Junior League, now taking the name Jr. Tag Battle of Glory (ジュニア・タッグバトル・オブ・グローリー, Junia Taggu Batoru Obu Gurōrī).
The tournament is contested in a single block round-robin format with all teams facing each other once. All matches have a thirty-minute time limit and in case of a time limit draw, both teams are awarded one point, while a win earns a team two points.[1] In case of a draw through a double countout, the match is declared a no contest with neither team being awarded a point.[1] After all teams have faced each other, the top two teams move onto the finals to determine the winner of the tournament.[1] Rankings in the tournament are not determined by head-to-head matches and in the event of more than two teams finishing clear of the other teams, extra matches will be held to determine the finalists.[1] Usually, the winners of the tournament earn themselves a shot at All Japan's secondary tag team championship, the All Asia Tag Team Championship, if not already the reigning champions.
Hikaru Sato holds the record for most Junior Tag League wins with five. Sato and Atsushi Aoki are the only team to have won the tournament more than once, having won it in 2014, 2015 and 2016.
