Ju-jitsu is a generic term for an almost undefinable system of fighting, primarily unarmed, but in some instance using weapons. Ju-jitsu techniques include punching, kicking, striking, throwing, holding, locking, choking and tying as well as the use of certain weapons. Ju-jitsu does not rely on brute strength but upon skill and finesse.

It is the use of minimum effort to achieve maximum effect. Applying this principle enables anyone, regardless of physique or stature, to control and release their energy to its greatest potential.

Ju-jitsu was incorporated into the Asian Games in 2018.

The ju-jitsu of the Hangzhou Asian Games will be held in Xiaoshan Linpu Gymnasium from October 5 to October 7, and the athletes will compete for 8 gold medals.
