Ne-waza is a term used in martial arts, particularly in judo and Brazilian jiu-jitsu, to describe ground techniques. It focuses on grappling and submissions, allowing practitioners to control their opponents while on the ground. Techniques include joint locks, chokes, and positional control, emphasizing leverage and technique over brute strength. In judo, ne-waza is an essential part of the sport, complementing standing techniques known as tachi-waza. Competitors often transition from standing to the ground during matches, where ne-waza skills can determine the outcome. Mastery of ne-waza enhances overall effectiveness in grappling-based martial arts.
