Wrestle Kingdom 9
Wrestle Kingdom 9 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, 2015. It was the 24th January 4 Tokyo Dome Show and the first event on the 2015 NJPW schedule. The event featured ten professional wrestling matches and one pre-show match, six of which were for championships.
Wrestle Kingdom VI
Wrestle Kingdom VI featured the NJPW return of Kazuchika Okada. Okada was a rookie in 2010, when NJPW, through their international connections, sent him to the American Total Nonstop Action Wrestling (TNA) promotion to gain experience and grow as a wrestler. During his one and a half years in TNA, Okada did little of note; he was dressed up like Kato from "The Green Hornet", dubbed "Okato" and made Samoa Joe's sidekick in an angle with D'Angelo Dinero, wrestling only a handful of actual matches. TNA's poor handling of Okada was one of the key factors in NJPW ceasing their relationship with the American promotion, which made Wrestle Kingdom VI the first Tokyo Dome show in five years to not feature any wrestlers from the company. On December 9, 2011, NJPW announced that Okada would return to the promotion at Wrestle Kingdom VI, facing Yoshi-Hashi, who was making his own return from the Mexican Consejo Mundial de Lucha Libre (CMLL) promotion, with whom NJPW also had a working relationship, where, unlike Okada, he had been wrestling a full schedule and improving. Upon his return to NJPW, Okada created himself a new villainous persona named "Rainmaker".
