The kimura submission BJJ practitioners rely on is one of the most versatile and recognizable techniques in grappling. Whether you are a beginner stepping onto the mats for the first time or an advanced competitor refining your attack system, the kimura remains a powerful shoulder lock that can be applied from multiple positions. In Brazilian Jiu-Jitsu, mastering fundamental submissions is essential, and the kimura stands out because of its effectiveness, control potential, and adaptability in both gi and no-gi training. Understanding how the kimura works, where it comes from, and how to apply it safely can significantly improve your overall grappling game.
Origins of the Kimura Submission
The kimura submission is named after the legendary Japanese judoka. He famously used this double wrist lock technique in a historic match against. The technique became widely associated with Kimura after that bout, and over time it was adopted and refined within.
Although the move existed in judo as a shoulder lock, Brazilian Jiu-Jitsu practitioners expanded its applications. Today, the kimura submission BJJ athletes practice is far more than a single finishing technique. It is also a control tool, a sweep setup, and a transition gateway.
What Is the Kimura Submission in BJJ?
The kimura is a figure-four shoulder lock that targets the opponent’s shoulder joint. It involves isolating one of the opponent’s arms, bending it behind their back, and applying rotational pressure. When executed correctly, it creates intense pressure on the shoulder, forcing the opponent to tap out to avoid injury.
The key to the kimura submission BJJ technique lies in control rather than brute strength. Proper grips, body positioning, and hip movement make the submission effective even against larger opponents.
Basic Mechanics of the Kimura
Step 1 Isolate the Arm
The first step is controlling your opponent’s wrist while keeping their elbow bent at approximately 90 degrees. This angle is crucial for maintaining leverage.
Step 2 Secure the Figure-Four Grip
You grab your opponent’s wrist with one hand, then thread your other arm under their upper arm to grab your own wrist. This creates the figure-four configuration that defines the kimura submission BJJ athletes practice.
Step 3 Apply Controlled Rotation
By lifting the opponent’s elbow and rotating their arm behind their back, pressure is applied to the shoulder joint. The motion should be controlled and gradual to ensure safety during training.
Common Positions to Apply the Kimura
From Closed Guard
Closed guard is one of the most common entries for the kimura. When an opponent posts their hand on the mat, it creates an opportunity to isolate the arm and attack.
From Half Guard
The kimura from half guard is popular in modern BJJ. It can be used not only as a submission but also to sweep or transition to the back.
From Side Control
When controlling an opponent from side control, isolating the far arm can lead directly to a powerful kimura finish.
From Standing or Takedown Scrambles
Advanced practitioners sometimes apply the kimura grip during scrambles or even from standing positions, transitioning smoothly to ground control.
Why the Kimura Is So Effective
- Works from multiple positions
- Provides strong control over opponents
- Useful for sweeps and transitions
- Effective in gi and no-gi
- Suitable for different body types
The kimura submission BJJ technique is not just about finishing. Many athletes use the kimura grip as a controlling position, sometimes referred to as the kimura trap system.
The Kimura Trap System
The kimura trap system involves maintaining the kimura grip while transitioning between positions. Instead of forcing the submission, practitioners use the grip to off-balance opponents, secure sweeps, or take the back.
This approach reflects the strategic depth of Brazilian Jiu-Jitsu. The kimura becomes more than a submission; it becomes a pathway to dominant control.
Common Mistakes When Attempting the Kimura
Relying on Arm Strength
One of the biggest mistakes beginners make is using only their arms to finish the submission. Proper hip movement and body positioning generate far more leverage.
Poor Wrist Control
If the opponent’s wrist is not tightly controlled, they can straighten their arm and escape.
Ignoring Opponent’s Defense
Experienced opponents may roll forward, grab their belt, or clasp their hands together to defend. Anticipating these reactions is essential.
Defending Against the Kimura
Understanding defense helps both attackers and defenders improve. Common defensive strategies include
- Straightening the arm before the figure-four is secured
- Rolling forward to relieve pressure
- Grabbing your own belt or clothing in gi matches
- Turning toward the attacker to reduce leverage
Recognizing these defenses allows practitioners to refine their kimura submission BJJ setups.
Safety Considerations in Training
The shoulder joint is vulnerable, and the kimura can cause serious injury if applied recklessly. Always apply pressure slowly and give your training partner time to tap. Communication on the mats is essential.
Coaches often emphasize control over speed. In competition, the submission may be applied quickly, but in the academy, safety comes first.
Gi vs No-Gi Applications
In gi training, practitioners can use lapels and sleeves to enhance control before transitioning to the kimura grip. In no-gi, body positioning and tight wrist control become even more important.
The kimura submission BJJ strategy adapts well to both formats, making it a universal technique across grappling disciplines.
Building a Game Around the Kimura
Some athletes build their entire strategy around kimura attacks. By constantly threatening the submission, they force opponents to react defensively. This creates openings for sweeps, back takes, and other submissions.
Drilling entries from guard, half guard, and side control can help integrate the kimura naturally into your game.
Physical Attributes and Leverage
The kimura does not require exceptional strength. Smaller practitioners often use it successfully against larger opponents because it relies on leverage and joint mechanics.
Flexibility, proper posture, and hip mobility contribute to smoother execution.
Competition Use
The kimura submission BJJ competitors favor is commonly seen in tournaments at all levels. From local competitions to international championships, the technique remains a reliable finishing tool.
Its versatility makes it particularly valuable in point-based formats, where transitions and control are as important as submissions.
The kimura submission BJJ practitioners study is one of the most essential techniques in grappling. With roots in judo and a strong presence in Brazilian Jiu-Jitsu, it has evolved into both a submission and a strategic control system. By mastering proper mechanics, understanding common defenses, and prioritizing safety, athletes can make the kimura a powerful part of their training and competition arsenal.
Whether used to finish a match, sweep an opponent, or transition to a dominant position, the kimura continues to prove its value on mats around the world. Consistent practice and thoughtful application ensure that this classic shoulder lock remains a cornerstone of effective Brazilian Jiu-Jitsu.
