Judo Level 5: Ude Hishigi Sankaku Gatame — A triangle with an elbow-joint purpose

腕挫三角固, ude-hishigi-sankaku-gatame, is a joint technique. Sankaku means triangle.

The legs restrict upper-body movement while arm control establishes the joint action. Separating these functions makes the clip easier to read.

Ude-hishigi-sankaku-gatame uses a triangular leg structure to control the upper body, but elbow control makes it kansetsu-waza. Kodokan includes rotational or extending arm action. Follow the controlled arm, not just the triangle.

A triangular shape appears in both this technique and Sankaku Jime, but their purposes differ. Not every triangle is a strangle.

Sankaku-jime can share a similar leg shape but is a strangle. A shared base does not make the controlling effect identical. Distinguish the leg structure from what is being done to the arm.

Let an instructor set the practice form. Do not unknowingly combine neck compression and elbow pressure. Stop and release immediately on a signal or discomfort.

The Level here refers to the IMAC Dojo curriculum. Use the article and clips to prepare questions and review them with your instructor. Practical training needs a suitable partner, space and controlled conditions.

Pause before the hands move and ask which arm is enclosed and where the elbow line lies. Do not combine neck and arm pressure experimentally to discover which technique is occurring.
