K-1 PREMIUM Dynamite!! (or simply Dynamite!!) was an annual kickboxing and mixed martial arts (MMA) event held in Japan by the Fighting and Entertainment Group (FEG). It began as a co-production between the Pride Fighting Championships (PRIDE) and FEG's K-1 group, with the first event being held on August 28, 2002. The inaugural event was referred to by K-1 as "Dynamite!!" while PRIDE called the event "Shockwave". Its live audience totaled 91,108 people, which is the largest on-record attendance for either organization and the largest attendance in the history of MMA.[1]
Even after the end of the participation of fighters from PRIDE, Dynamite!! events remained unique from other K-1 events in that they featured cards with both MMA and kickboxing bouts on them. Later, the Dynamite!! events became co-productions between K-1 and FEG's own MMA promotions — first Hero's and later DREAM. In addition to FEG's own MMA promotions, the Dynamite!! 2009 event was co-produced with the Sengoku Raiden Championship (SRC) MMA promotion.
In 2007, the only Dynamite!! event to be hosted outside of Japan, Dynamite!! USA, was held. Dynamite!! USA was a co-production with Elite Xtreme Combat (EliteXC) and the only pure MMA event of the Dynamite!! series.
