Overview

Ude-Garami attacks a bent arm using a figure-four grip to rotate the shoulder joint. Known as the "Kimura lock" in BJJ and MMA (named after Masahiko Kimura, who used it to defeat Hélio Gracie in 1951), it applies torque to the shoulder by rotating the forearm in a direction the joint cannot follow. It can be applied from mount, side control, guard, or as a counter to Seoi-Nage entry.

How to Execute

Ude-Garami — Step by Step

  1. 1

    Isolate uke's arm in a bent position

    Control uke's right arm bent at approximately 90 degrees, with their elbow on the mat and forearm pointing upward. Their hand should be beside their head, palm facing down.

  2. 2

    Grip uke's right wrist with your left hand

    Your left hand grips uke's right wrist from on top, securing the bent arm.

  3. 3

    Thread your right arm under uke's right upper arm

    Reach your right arm under uke's right upper arm/tricep area and grip your own left wrist to form the figure-four. This is the control grip.

  4. 4

    Apply the shoulder rotation

    Rotate uke's forearm upward (toward their head) while simultaneously pulling their upper arm inward with your right arm. The figure-four creates a lever that rotates the shoulder joint.

  5. 5

    Maintain posture and increase pressure progressively

    Drive uke's hand toward their head and beyond while maintaining the figure-four. Increase pressure incrementally and release immediately on uke's tap.

Key Principles

What Makes It Work

  • The figure-four grip is the core of the technique — without it, rotation is limited.
  • The forearm rotates upward toward uke's head — the direction that stresses the shoulder.
  • Keep uke's elbow close to their body. If the elbow flares out, the shoulder angle changes unfavorably.
  • This technique can be applied from multiple positions — mount, side control, North-South, even standing as a counter to Seoi-Nage entry.
Common Mistakes

What to Avoid

#1 Common Mistake

Figure-four grip too shallow

Thread your arm deeply under uke's upper arm to get the figure-four wrist-to-wrist. Shallow grip means less control.

#2 Common Mistake

Rotating the forearm toward the feet (wrong direction)

Rotate toward the head — driving uke's hand toward their shoulder and beyond. Downward rotation is away from the stress angle.

#3 Common Mistake

Elbow allowed to flare outward

Keep uke's elbow pinned close to their side. Use your body weight to hold it in place.

#4 Common Mistake

Applying suddenly without warning

Apply progressively. Ude-Garami can cause serious shoulder injury if torque is applied rapidly.

When to Use

Best Moments to Apply Ude-Garami

Ude-Garami is effective whenever uke's arm is bent and you control their upper body. Classic setup: from side control, pin uke's near arm, thread the figure-four, apply. Also a powerful counter to Seoi-Nage — when tori enters for the throw and exposes their bent arm, uke can apply Ude-Garami around tori's shoulder. In BJJ/MMA it is known as the Kimura and is commonly used from the guard; note that guard-based ne-waza is restricted in IJF competition judo.

FAQ

Frequently Asked Questions

What is the relationship between Ude-Garami and the "Kimura" in BJJ/MMA?
They are the same technique. "Kimura" is the name used in BJJ and MMA, honoring Masahiko Kimura, who defeated Hélio Gracie with this technique in 1951. In judo it is called Ude-Garami (arm entanglement). The mechanics are identical.
What is the difference between Ude-Garami and Juji-Gatame?
Ude-Garami attacks a bent arm by rotating the shoulder joint with a figure-four grip. Juji-Gatame (armbar) attacks a straight arm by hyperextending the elbow. Ude-Garami works when the arm is bent; Juji-Gatame requires a straight arm.
Is Ude-Garami allowed in judo competition?
Yes, for adult competitors. Under IJF rules, kansetsu-waza is restricted for younger competitors. Check your national federation rules for age group competitions.
Can Ude-Garami be applied as a counter to Seoi-Nage?
Yes — this is one of the most effective counters. When tori enters for Seoi-Nage and bends forward, their arm is in a bent position and exposed. Uke can apply Ude-Garami around tori's exposed shoulder as they enter.
