Dominion 6.9 in Osaka-jo Hall (2018): WrestleFile Historical Verdict

El Desperado and Yoshinobu Kanemaru defended the IWGP Junior Heavyweight Tag Team Championship against SHO and YOH of Roppongi 3K in the 9:29 Dominion 2018 opener. Desperado pinned SHO with El Es Claro after Suzuki-gun attacked before the match began. The title stayed with the defending pairing, a notable exception on a card where five other championships would change hands. SHO was the wrestler pinned; YOH was his partner and did not take the decision. This relatively short junior tag defense should not be combined with the Young Bucks' later victory in the senior IWGP tag title match. The C+ grade recognizes its precise result and role in the show without treating it as one of the final championship spectacles.

Juice Robinson and David Finlay defeated Jay White and YOSHI-HASHI in 7:26 when Robinson pinned White with Pulp Friction. White was the reigning IWGP United States Heavyweight Champion, but this was a non-title tag, so Robinson did not take his belt at Dominion 2018. The fall nevertheless advanced the Robinson–White challenge that later developed into a United States title match. Finlay's support helped secure the team result while Robinson personally scored the decisive pin, a distinction lost when the bout is described as only a tag win. The C grade accounts for a short contest with a future singles implication instead of inventing a championship change or a longer, main-event-caliber exchange.

Minoru Suzuki and Zack Sabre Jr. defeated Tomohiro Ishii and Toru Yano in 8:42 at Dominion 2018. Sabre submitted Yano with a modified Jim Breaks Armbar, the fall recorded by the archived New Japan results, while Suzuki and Ishii repeatedly brawled away from the submission. Some accounts emphasize that both Suzuki-gun wrestlers had holds applied in the closing moment, but the result assigns the decision to Sabre over Yano. No tag or singles championship was being awarded in this supporting match; it was a Suzuki-gun-versus-CHAOS confrontation ahead of the five separate senior title changes. Its C+ score reflects a clear technical submission in a brief tag rather than a title defense or a pin by Suzuki on Ishii.

Michael Elgin defeated defending NEVER Openweight Champion Hirooki Goto and Taichi in 13:46 to win the championship at Dominion 2018. The decisive pin came on Taichi after the Elgin Bomb, so Goto lost the title without personally taking the fall. It was a three-way singles championship match, not the final of a separate tournament. The outcome began the card's extraordinary succession of title changes: the Young Bucks, Hiromu Takahashi, Chris Jericho and Kenny Omega would also take belts later that night. Its B- grade acknowledges the meaningful championship result while avoiding an invented exchange of offense or a false finish on Goto. Distinguishing the title loser from the actual pinned wrestler gives a reader a more accurate record of how the three-way ended.

Matt and Nick Jackson defeated EVIL and SANADA in 15:03 to win the IWGP Tag Team Championship for the first time. Matt pinned SANADA after More Bang for Your Buck, placing the decisive fall on SANADA rather than EVIL. The Young Bucks had previously been associated chiefly with New Japan's junior heavyweight tag division; this victory moved them into the senior tag championship picture. EVIL and SANADA came in as champions and lost their belts, so this was a title change rather than a successful defense. The B- assessment recognizes a clearly recorded tag-team milestone, though the main event later became the card's most widely discussed match. The championship victory should also stay separate from the Bullet Club Elite six-man involving Cody, Hangman Page and Marty Scurll on the same show.

Cody, Hangman Page and Marty Scurll defeated Rey Mysterio, Jushin Thunder Liger and Hiroshi Tanahashi in 11:35 in Dominion 2018's non-title six-man. Cody pinned Liger after Cross Rhodes, so the legendary Liger was the wrestler taking the fall rather than Rey Mysterio or Tanahashi. The match gave the Osaka crowd a rare combination of Mysterio and Liger on the same team, while Page and Scurll joined Cody on the opposing Bullet Club side. It did not affect any of the five championships that changed hands on the card. The C+ evaluation acknowledges the novelty of the participants and the actual recorded finish, without crediting it with the junior or heavyweight singles belts defended in the later matches.

Hiromu Takahashi defeated Will Ospreay in 20:20 with the Time Bomb to win the IWGP Junior Heavyweight Championship at Dominion 2018. Takahashi had just won the Best of the Super Juniors 25, so the challenge was the immediate championship payoff to that tournament victory. Ospreay was the defending champion; Takahashi ended his reign here rather than at an unrelated G1 or Tokyo Dome event. The B match grade and 7.8 score recognize the length, finish and prominent junior title consequence without adopting external star ratings as WrestleFile's own assessment. Coming after the Bullet Club Elite versus Tanahashi/Liger/Mysterio tag, it was the first of three concluding singles championship decisions. The result should not be merged with the earlier junior tag title defense retained by Suzuki-gun.

Chris Jericho defeated defending IWGP Intercontinental Champion Tetsuya Naito with the Codebreaker in 17:16 to win the championship at Dominion 2018. The match was notably aggressive, with Jericho striking Naito outside the ring and escalating the confrontation beyond a conventional title defense. After the pin Jericho continued attacking the former champion until EVIL came out to stop him. The result was a genuine title change, not a no-contest or disqualification caused by the attack afterward. Its B- grade reflects a meaningful championship decision while acknowledging that the violence and postmatch angle shaped how the bout is remembered. This was the final singles championship change before Kenny Omega faced Kazuchika Okada in the much longer two-out-of-three-falls heavyweight main event.

Kenny Omega defeated Kazuchika Okada two falls to one in 64:50 to win the IWGP Heavyweight Championship at Dominion 2018, ending Okada's 720-day title reign. Their no-time-limit match was the fourth major singles meeting of a rivalry that had included a 60-minute draw in 2017. Okada won the first fall at 28:47, with the exact roll-up or Rainmaker attribution differing among live and archival accounts; Omega leveled it with a One-Winged Angel at a cumulative 47:57 and won the deciding fall with another at 64:50. Kota Ibushi accompanied Omega, and the Young Bucks joined the postmatch celebration. This is a rare title change in a two-out-of-three-falls bout rather than a one-fall retention. The B+ grade is WrestleFile's own evaluation; it does not claim to duplicate a prominent outside seven-star appraisal. The historical significance lies in the decisive end of Okada's record reign and Omega's first IWGP heavyweight championship.
