Wrestle Kingdom 10
Wrestle Kingdom 10 featured ten 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.
Wrestle Kingdom 10 was main evented by Kazuchika Okada defending the IWGP Heavyweight Championship against Hiroshi Tanahashi. Okada won the title on July 5, 2015, by defeating A.J. Styles at Dominion 7.5 in Osaka-jo Hall, while Tanahashi became the number one contender at the Tokyo Dome by winning the 2015 G1 Climax, defeating Shinsuke Nakamura in the finals on August 16. On the road to the Tokyo Dome, Okada retained his title in a rematch with A.J. Styles, while Tanahashi defended his title match contract against Bad Luck Fale and Tetsuya Naito, the two wrestlers who had defeated him during the G1 Climax, leading to the Tokyo Dome match being made official on October 12. This would mark the seventh IWGP Heavyweight Championship match between Okada and Tanahashi with both wrestlers having won three of the previous matches. This also marked Tanahashi's sixth Wrestle Kingdom in a row main event with him having won all five previous main events, two of which were against Okada.
