On July 30, 2013, All Japan Pro Wrestling announced a new single-elimination tournament, set to take place the following September. Masanobu Fuchi, advisor to the AJPW board of directors, announced that the tournament was open to both Japanese and foreign wrestlers regardless of their weight divisions. This sets it apart from AJPW's top tournament, the Champion Carnival, which is generally exclusive to heavyweight wrestlers. Since its inception, the tournament has been subtitled "Open Championship", which was a similar openweight tournament held by AJPW in 1975. In the spirit of keeping the new tournament different from the Champion Carnival, the elimination format was set for use. Fuchi hailed Ōdō Tournament as the start of AJPW's rebirth, coming in the heels of a that led to the formation of the Wrestle-1 promotion. The winner of the tournament, if not already the reigning champion, will become the number one contender to the Triple Crown Heavyweight Championship.
The 2014 Ōdō Tournament took place between September 15 and 28 and featured sixteen wrestlers. The participants and brackets were revealed on August 17. Included were the reigning Triple Crown Heavyweight Champion Joe Doering, the defending Ōdō Tournament winner Akebono and one qualifying match, set for August 30 between Sushi and Yohei Nakajima. Joe Doering, the reigning Triple Crown Heavyweight Champion, was eliminated from the tournament in his first round match on September 15 by Go Shiozaki, while veteran wrestler and AJPW's new president Jun Akiyama, for the second year in a row, was also eliminated in his first round match by Kento Miyahara. Akebono, the defending Ōdō Tournament winner, was eliminated from the tournament in the semifinals on September 22 by Suwama.
