The Fantastica Mania 2015 event was a series of six professional wrestling events in Japan, co-produced by the Japanese promotion New Japan Pro Wrestling (NJPW) and the Mexican promotion Consejo Mundial de Lucha Libre (CMLL) and took place between January 13 and 19, 2015. The 2015 shows were the fifth time that NJPW and CMLL have co-promoted shows in Japan under the Fantastica Mania name. The 2015 event featured six shows in total, one more than the Fantastica Mania 2014 series, and the most shows of any year to date. The 2015 show was the first time the joint show will be held in Takamatsu and Kyoto while it had previously held shows in both Tokyo and Osaka.
The events featured six to eight professional wrestling matches on each event. The 2015 Fantastica Mania series of shows were the fifth year in a row where Japanese wrestling promotion New Japan Pro Wrestling (NJPW) has promoted a series of shows in Japan along with their Mexican partner promotion Consejo Mundial de Lucha Libre (CMLL). The 2015 series of shows were show 13 through 18, a total of 6 shows, the highest number of any year up until that point. The show in Takamatsu, Japan on January 14 will be the first time Fantastiamaniac takes place in Takamatsu. In the summer of 2014 Bárbaro Cavernario won the 2014 2014 version of the En Busca de un Ídolo ("In search of a Idol") tournament and as part of winning the tournament he was guaranteed participation in the 2015 Fantastica Mania series of matches. When CMLL and NJPW made the announcement of the six dates in 2015 they also announced Bárbaro Cavernario and Último Guerrero as the first two Mexican competitors for the series of shows.
