The International Wrestling Association of Japan, more commonly known as IWA Japan, was a Japanese professional wrestling promotion operating from 1994 to 2004 and again from 2010 to 2014. It was formed by Víctor Quiñones as a successor to the W*ING promotion, which was folding at the time as a rival to Frontier Martial-Arts Wrestling (FMW), the pioneer of deathmatch wrestling in Japan and the only deathmatch promotion in Japan at the time. Most of the wrestlers jumped ship to Quiñones' new IWA Japan group. He found a sponsor in Tatsukuni "Kinroku" Asano, a business man who owned several restaurants in Tokyo and had bought and run several wrestling shows prior to IWA Japan.
