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.
King of Pro-Wrestling (2014)
In the semi-main event, Kazuchika Okada was booked to defend his certificate for an IWGP Heavyweight Championship match at Wrestle Kingdom 9 in Tokyo Dome, which he had obtained by winning the 2014 G1 Climax, against Tetsuya Naito. During G1 Climax, Okada had been defeated by Naito, which resulted in him nominating Naito as his next challenger for the certificate. In the main event, Bullet Club's A.J. Styles would make his third defense of the IWGP Heavyweight Championship against Hiroshi Tanahashi. After failing to capture the IWGP Heavyweight Championship from Okada at the 2013 King of Pro-Wrestling, Tanahashi announced that he was leaving the title picture. However, after defeating Katsuyori Shibata at Destruction in Kobe, Tanahashi announced he was back and looking for a shot at A.J. Styles. Tanahashi and Styles previously faced off in Ryōgoku Kokugikan on February 17, 2008, and more recently met in a special non-tournament singles match during the final day of the 2014 G1 Climax. Tanahashi won the match, but was afterwards attacked by Bullet Club's newest member, Jeff Jarrett. Jarrett did not make another appearance for NJPW for two months, but was working behind the scenes on getting Wrestle Kingdom 9 in Tokyo Dome broadcast on the American PPV market. On September 29, Jarrett announced he was returning to NJPW at King of Pro-Wrestling.
