The Legend Masahiko Kimura Teaches A Rolling Kimura Set Up

Certain terms are used to specify a medial keylock technique in combat sports. In judo, it is known as gyaku ude-garami (reverse arm entanglement) or simply ude-garami. Brazilian Jiu-Jitsu refers to it as a Kimura, while catch wrestling may call it a chicken wing or double wrist lock. Another name is reverse keylock.

The application of this technique is similar to an Americana, except reversed. It requires some open space behind the opponent to be effective and can be performed from side control or guard positions. Unlike an Americana, the opponent’s wrist is grabbed with the same-side hand while the opposite arm is placed behind their arm and also grabs their wrist, forming a figure-four shape.
By controlling the opponent’s body and torquing the arm away, pressure is put on the shoulder joint and possibly the elbow joint as well, depending on the angle. In some variations, the opponent’s arm is brought behind their back into a position resembling a hammerlock. This technique was popularized by judoka Masahiko Kimura, who famously used it to defeat Brazilian Jiu-Jitsu founder Hélio Gracie. Since an Americana is a reverse Kimura, UFC announcer Bruce Buffer still refers to fights won by Americana as being finished by a Kimura.
