Wrestle Kingdom 8 in Tokyo Dome was a professional wrestling pay-per-view (PPV) event produced by the New Japan Pro-Wrestling (NJPW) promotion, which took place at the Tokyo Dome in Tokyo, Japan on January 4, 2014. It was the 23rd January 4 Tokyo Dome Show and the eighth held under the "Wrestle Kingdom" name. Like the previous year, the event aired worldwide on internet pay-per-view (iPPV). Wrestle Kingdom is traditionally NJPW's biggest event of the year and has been described as their equivalent to WWE's WrestleMania. The event featured ten matches, six of which were contested for championships. For the first time in twenty years, the National Wrestling Alliance (NWA) World Heavyweight Championship was defended during the event with NWA representative Rob Conway defending against Satoshi Kojima. The event was headlined by a double main event; Shinsuke Nakamura defending the IWGP Intercontinental Championship against Hiroshi Tanahashi and Kazuchika Okada defending the IWGP Heavyweight Championship against the winner of the 2013 G1 Climax, Tetsuya Naito. A fan vote decided the order in which the two matches took place during the event; the Heavyweight Championship match went first and the Intercontinental Championship match was the final match of the event. The event also featured outside participation from Wrestle-1 representative Keiji Mutoh, who worked under his Great Muta character. The event also featured appearances by Harley Race, Marty Friedman and Stan Hansen. Production Background In addition to airing on traditional pay-per-view (PPV) in Japan, the event also aired worldwide on internet pay-per-view (iPPV) through Niconico and Ustream. Storylines Wrestle Kingdom 8 featured eleven professional wrestling matches that involved different wrestlers from pre-existing scripted feuds and storylines. Wrestlers portrayed villains, heroes, or less distinguishable characters in the scripted events that built tension and culminated in a wrestling match or series of matches. On August 11, 2013, Tetsuya Naito defeated Hiroshi Tanahashi in the finals to win the 2013 G1 Climax. The following day, Naito was given a contract granting him a shot at the IWGP Heavyweight Championship in the main event of Wrestle Kingdom 8. Despite being a clean cut babyface, Naito was thoroughly disliked by NJPW fans, which led to NJPW changing their course of action, announcing a fan vote to decide whether the match between him and Okada or an IWGP Intercontinental Championship match between Shinsuke Nakamura and Hiroshi Tanahashi would main event Wrestle Kingdom 8. Nakamura and Tanahashi won the vote with
