Background and the debut of his "Rainmaker" persona 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.
Storylines Wrestle Kingdom VI featured twelve
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. ==Event==
