Ultimate Sankaku Guide: Techniques, Transitions, and Variations

In martial arts, Sankaku refers to a specific technique with great significance. Sankaku, which translates to “triangle” in Japanese, involves utilizing the legs to create a triangular configuration, allowing for various submissions and control positions.

This technique has found its place in different martial arts disciplines, including Brazilian Jiu-Jitsu, judo, and mixed martial arts. The Sankaku technique uses leverage, angles, and pressure to immobilize opponents or execute submissions. 

Practitioners can effectively restrict an opponent’s movement by employing the legs to form a triangle, apply joint locks, or induce chokes. The versatility and effectiveness of Sankaku make it a fundamental skill for martial artists of all levels.

Sankaku, which roots in traditional Japanese martial arts, has become a well-known technique in various combat disciplines worldwide. Historically, Sankaku emerged as a strategic method to control opponents and secure submissions using the legs. 

Over time, it has evolved and found its place in modern grappling systems, particularly in Brazilian Jiu-Jitsu and other ground-based martial arts.

The significance lies in its ability to provide a versatile and practical approach to offensive and defensive grappling. By leveraging the triangular configuration formed by the legs, practitioners can establish dominant control positions, apply joint locks, or initiate chokes. 

Sankaku’s effectiveness stems from its focus on exploiting leverage, angles, and pressure to immobilize opponents and create submission opportunities.


Fundamental Principles and Concepts Associated with Sankaku

  1. Triangle Control: At the core is the concept of triangle control. This refers to utilizing the legs to create a triangular shape around an opponent’s limb, neck, or body. The triangle offers stability, control, and mechanical advantage, enabling effective submissions and control positions.
  2. Angles and Pressure: Sankaku relies heavily on utilizing optimal angles and pressure to maximize control and effectiveness. By positioning the legs and hips at specific angles relative to the opponent’s body, practitioners can generate immense pressure, restricting movement and facilitating submissions.
  3. Active Hip Movement: Effective execution requires dynamic and active hip movement. By actively engaging the hips, practitioners can generate the necessary force to secure and maintain control and transition between different variations and positions.
  4. Grips and Control Points: Proper gripping and control points play a vital role in techniques. Whether it’s gripping the opponent’s sleeve, collar, or leg, understanding how to establish and maintain effective grips enhances the effectiveness of techniques.
  5. Flow and Transitions: Sankaku is not merely a static position but involves fluid transitions and adaptability. Filling between different variations and seamlessly transitioning from one position to another allows practitioners to capitalize on openings and maintain control throughout grappling exchanges.
  6. Awareness of Counters and Escapes: Understanding the common counters and escapes is essential for offense and defense. Being aware of potential escapes allows practitioners to anticipate and counteract their opponent’s actions while maintaining control and increasing the success rate of submissions.

Sankaku Techniques

Triangle Choke

The Triangle Choke is one of the most iconic and practical submissions in Sankaku. It involves using the legs to create a tight triangular grip around the opponent’s neck, cutting off their blood supply and airway. To execute the Triangle Choke successfully, practitioners must follow these key steps:


Setup: The setup for the Triangle Choke begins by controlling an opponent’s posture and creating space for the legs to maneuver. This can be achieved from various positions, such as the Closed Guard, or when transitioning from other techniques. Proper grip control and hip movement are crucial during the setup phase.


Execution: Once the setup is established, practitioners must wrap their legs around the opponent’s neck, with one leg over the back of the opponent’s neck and the other under their armpit. The practitioner then locks the position by clasping the ankle and applying inward pressure with the legs while maintaining control of the opponent’s posture.



Common Mistakes: When performing the Triangle Choke, inevitable mistakes can hinder its effectiveness. These include failing to adequately control the opponent’s posture, using incorrect leg placement, or needing proper hip movement. 



It targets the opponent’s arm, hyperextending the elbow joint and creating immense pressure. The Armbar from Sankaku involves the following elements:


Setup: The Armbar can be initiated by transitioning from the Triangle Choke or directly attacking the arm from a Sankaku position. The key is to control the opponent’s arm, isolate it from their body, and secure a firm grip on the wrist or forearm.


Grips: Proper grip control is crucial for effectively executing the Armbar. This includes establishing a solid grip on the opponent’s arm while ensuring control of their posture and preventing any escapes or counters.


Counters and Escapes: As with any submission, the Armbar has counters and escapes that opponents can employ to defend against. These may involve postural adjustments, grip breaks, or specific movements to relieve pressure on the arm.
