Wrestle Kingdom 12
Behind the scenes, Jericho became part of a group of people that started pushing for the show to air on American pay-per-view (PPV) for the first time since Wrestle Kingdom 9 in 2015. Some in NJPW felt that airing the show through NJPW World would be enough, hoping that the Jericho signing would increase subscriber numbers. While NJPW was now considered more popular than in 2015, when Wrestle Kingdom 9 did 14,000 buys on American PPV, it was noted that the 2018 show would take place early Thursday morning in the United States as opposed to a weekend like it did in 2015, which was seen as a major negative in terms of getting buys from the country. In late November, it was reported that NJPW had turned down Fite TV's offer for PPV rights outside of Japan and would not be allowing the event to air on American PPV, wanting their streaming service to be the only way to see the event live. On December 3, it was announced that the top matches from the show would air on AXS TV on January 6, 2018, as part of an 11-hour block of NJPW programming with additional matches airing between January 12 and February 9. Five matches, including the top three matches, will air on TV Asahi as part of a special episode of "World Pro Wrestling" on the night of January 4.
Wrestle Kingdom 9
Wrestle Kingdom 9 broke Yuji Nagata's streak of consecutive January 4 Tokyo Dome Show appearances at 21 by being featured on the pre-show instead of the main card. In an interview, Nagata said that he felt slighted and thought about quitting when he was relegated to the pre-show. The day after the event, he was scheduled to challenge Shinsuke Nakamura for the IWGP Intercontinental Championship, returning to the IWGP main-event picture for the first time in years. Although Nagata received his title shot at NJPW The New Beginning in Sendai, he was defeated by Nakamura. Nakamura's Wrestle Kingdom 9 opponent, Kota Ibushi, won the 2015 New Japan Cup tournament on March 15 by defeating Hirooki Goto in the finals, thus earning the right to choose a championship to challenge. Ibushi picked a match with A.J. Styles for the IWGP Heavyweight Championship (leaving Goto to challenge Nakamura). Ibushi failed in his title challenge on April 5 at NJPW Invasion Attack 2015, and Goto defeated Nakamura on May 3 at NJPW Wrestling Dontaku 2015 to become IWGP Intercontinental Champion.
