Ne-Waza has heavy focus on ground fighting and submissions. The discipline is hugely popular around the world and seen in professional MMA promotions such as the Ultimate Fighting Championship.
It was included by the JJIF in 2010 and first featured at the World Games in 2013.
Punches and kicks are not allowed in Ne-Waza, with most of the fight on the floor.
The goal is to win by submission with a lock on the joints or strangulation, or by points.
During a period of six minutes, it is possible to gain points for throws, takedowns, controlling positions and certain actions that give an advantage in the progression of the fight.
The Ne-Waza system is also called "human chess" due to its strategic and tactical nature.
