Judo Level 4: Ude Hishigi Ashi Gatame — Read foot control together with body position

腕挫脚固, ude-hishigi-ashi-gatame, is a joint technique. 脚 identifies the practitioner’s leg; 腕 identifies the arm.

Kodokan’s example approaches the side of a prone partner and uses the foot to control an arm. Read contact together with torso alignment, with an instructor checking actual placement.

Ashi-gatame uses tori's leg to control uke's arm. Kodokan's example has uke prone and a leg hooking the arm to control the elbow line. It is not a leg lock despite the word ashi. Read the arm and uke's body position together.

Hiza Gatame names the knee’s role, while this technique uses the foot or leg. Neither means controlling the partner’s leg. Ask whose body part the name describes.

Hiza-gatame also involves a leg, but the control points are not interchangeable. Distinguish a working knee from a leg retaining the arm in ashi-gatame. Do not automatically substitute terminology from another martial art.

Check foot placement with an instructor without joint pressure. Do not stamp or drop weight to test the result; stop immediately on signal.

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.

A low camera angle can conceal upper-arm restraint. Record what is hidden and ask your instructor rather than filling the gap by twisting a partner's arm. Video study should produce positional questions before pressure is added.
