The underground martial arts industry refers to the different organisations that run business, entertainment and other enterprises with martial arts as the core.

The underground martial arts industry in Japan is composed of many organisations with the Kengan matches being the largest and most prominent of them all. The underground battle industry also includes Bishamon, Purgatory, the yakuza-funded armed death matches known as the Death Fights, East Japan-based Underground -1 and the organisation with the most radical rules of them all Slaughter Colosseum. Purgatory and Bishamon are the largest organisations in the Japanese underground battle industry after the Kengan matches.[1]

China also has an underground martial arts promotion known as Heroic Tales, based in Beijing, which is divided into weight classes.[2]

Other underground martial arts arenas are based in Brazil, Italy and United Kingdom.
