Judo derives from Jiu-Jitsu, where all joints in the body (including leg, back, fingers etc) can be locked, to devastating affect. The original Judo allowed for a much wider set of locking techniques than are permitted in the modern sport, in which only Arm-Locks are legitimate techniques.

The 10 standard Kodokan techniques of Kansetsu-Waza comprise 9 arm-locks and one leg-lock (Ashi-Garami). Ashi-Garami is one of the four formally forbidden techniques (Kinshi-Waza), although the study of it is retained through the Katame-No-Kata.

A technically challenging 'figure-four' armlock, Ude-Garami places a sideways pressure on the elbow joint in a reverse direction to other typical armlocks. Mastered by the Judo prodigy Masahiko Kimura (in 1935 at the age of 18 he became the youngest ever Godan (5th degree black belt)) : in Brazilian Jiu-Jitsu this technique is known as the 'Kimura'.



Arm Locking/Crushing Straight Control

The 'straight' armlock is rarely used to submit an opponent in sparring (Randori) or competition as it is relatively easily to escape. Ude-Gatame is typically used in a standing position to distract an opponent, or on the ground as a transition to another Kansetsu-Waza, or Osaekomi-Waza (pinning-holding technique).

Arm Locking/Crushing Cross Control

Possibly the most common, popular and powerful of the Kansetsu-Waza in modern Judo. The cross arm lock (commonly referred to as Juji-Gatame) can be executed from many different angles, and there are a multitude of entries into the technique.



Arm Locking/Crushing Knee Control

A powerful, straight armlock, applied on an opponent face-down on the ground, using the knee.



Arm locking/Crushing Armpit Control

A classic of self-defence, this armlock is executed with Uke facing the floor, standing or on their stomach, while Tori has uke's arm trapped with the elbow beneath Tori's armpit. Tori lifts uke's hand, causing hyperextension of the elbow joint in a similar manner to Ude-Hishigi-Juji-Gatame.



Arm Locking/Crushing Stomach Control

A Hyper-extension of the opponent's arm across the stomach, again there are many entries into this technique, standing or on the ground.



Arm Locking/Crushing Leg/Foot Control

Hyper-extension of Uke's straight arm across Tori's leg, or using the leg/foot.



Arm Locking/Crushing Hand Control

Hyper-extension of Uke's straight arm across Tori's arm, or using the hand.



Arm locking/Crushing Triangle Control

Sankaku is a control usually applied with the legs to form a triangle, capturing both the opponent's arm and neck. It can result in a strangle, a hold or in this case a position from which to effect an armlock. See also Sankaku-Jime (Strangle) or Sankaku-Osae-Gatame (Hold).




Preserved in the Katame-no-Kata, Ashi-Garami is a technique forbidden in Randori and competition. (See 'Kinshi-Waza')
