Dominion 6.9 in Osaka-jo Hall (2019)

Dominion 6.9 in Osaka-jo Hall was officially announced on January 4, 2019, during Wrestle Kingdom 13. The event is NJPW's biggest between January's Wrestle Kingdom 13 and July–August's G1 Climax tournament.[2]

Dominion 6.9 in Osaka-jo Hall featured professional wrestling matches that involve different wrestlers from pre-existing scripted feuds and storylines. Wrestlers portray villains, heroes, or less distinguishable characters in the scripted events that built tension and culminate in a wrestling match or series of matches.[3]

After losing the IWGP Intercontinental Championship at Wrestle Kingdom 13 in Tokyo Dome, Chris Jericho expressed interest in challenging for the IWGP Heavyweight Championship at a later date.[4] At Wrestling Dontaku 2019, following a successful title defense by Kazuchika Okada against Sanada, Jericho announced (on a pre-taped video package) that he would be challenging the champion Okada at this event.

At this year's New Japan Cup, Kota Ibushi defeated the then-IWGP Intercontinental Champion Tetsuya Naito in the first round, eventually setting a championship match for G1 Supercard at Madison Square Garden. There, Ibushi again defeated Naito to become Intercontinental Champion for the first time. On April 20, at Sengoku Lord in Nagoya, following Ibushi's first defense against Zack Sabre Jr., Naito went to the ring and challenged him for a rematch. Ibushi accepted the challenge and the match was scheduled for this show.

At this year's New Japan Cup, Tomohiro Ishii met Taichi in the second round, successfully defeating him. Later in the year, at Wrestling Dontaku 2019, Taichi went on to capture the NEVER Openweight Championship from Jeff Cobb while Ishii defeated Evil in a special singles match. At the Ishii vs. Evil post-match backstage interview, Taichi offered a title challenge to Ishii, with Ishii accepting. The match was then scheduled for this event.

On June 5, 2019, Will Ospreay was crowned the Best of the Super Jr. 26 tournament winner, defeating Shingo Takagi in the final at Ryōgoku Sumo Hall. By virtue of winning the tournament, he got the right to challenge the current IWGP Junior Heavyweight Champion Dragon Lee at this year's Dominion event.

After losing to Will Ospreay at the Best of the Super Jr. 26 Finals, Shingo Takagi asked to wrestle against a heavyweight at Dominion. His request was granted and will face Satoshi Kojima at this event.

At Honor Rising: Japan 2019, the Guerrillas of Destiny (Tama Tonga and Tanga Loa) won the IWGP Tag Team Championship for the fifth time when they defeated the then-champion team of Los Ingobernables de Japón (Evil and Sanada). At G1 Supercard, they won the ROH World Tag Team Championship by defeating champions Villain Enterprises (PCO and Brody King) in a winner takes all four-way tag team match for both the IWGP and ROH World Tag Team Championships which also included Evil and Sanada and The Briscoe Brothers (Jay Briscoe and Mark Briscoe). At War of the Worlds: Chicago, while Evil and Sanada defeated the team of Satoshi Kojima and Yuji Nagata, the Guerrillas of Destiny successfully defended the ROH titles against The Briscoe Brothers. Following that match, Evil and Sanada confronted the Guerrillas declaring themselves their next challengers. At a backstage interview in Best of the Super Jr. 26: Final, the Los Ingobernables de Japón team confirmed that they would be challenging for the IWGP Tag Team Championship at this event.
