Dominion is an annual professional wrestling event promoted by New Japan Pro Wrestling (NJPW). The event has been held annually since 2009 as a pay-per-view (PPV). From 2013 to 2014, the event also aired outside Japan as an internet pay-per-view (iPPV). Since 2015, the event has aired worldwide on NJPW's internet streaming site, New Japan Pro Wrestling World. Dominion is the first major event following the Best of the Super Juniors tournament and usually includes a match, where the tournament winner challenges for the IWGP Junior Heavyweight Championship, assuming the champion has not won the tournament. In recent years, Dominion has developed into one of NJPW's showcase events and it is considered the biggest event since the January 4 Dome Show. The first six Dominions took place in June, but in 2015, the event was moved to July, only to be moved back to June the following year.
