Notes
Kata gatame (head-and-arm choke) appears in 17 passages across 4 books. The arm triangle traps the opponent's own arm against their neck, using the attacker's shoulder as the choking surface. One of the most powerful chokes from side control. (4 books; Kano, Kodokan Judo; Kyokushin manuals)
Frequently Asked Questions
What's the most common mistake people make when finishing the kata-gatame arm triangle?
The most common mistake is trying to push your shoulder into the opponent's face rather than using proper choking mechanics. Instead, you need to cut off both carotid arteries by getting your arm deep and pulling it all the way through to close off the space between the opponent's neck and your arm.
How should I position my opponent's arm to set up the kata-gatame effectively?
You want to get the opponent's elbow above their shoulder line—not just halfway through. Walk your head out and to the end of the lever, then push at the elbow (not at the armpit) to extend their arm, since people are stronger close to their hips and weaker the further you move them away.
What should I do if my opponent tries to turn away to escape the arm triangle?
When your opponent turns away, use your grip to pull through into a back take position. Get the seat belt grip behind the shoulder, lean forward, step over, and pull your heel tight toward their hip to prevent them from getting their knees in and escaping.
How should I apply pressure when finishing the arm triangle to avoid gassing out?
Build pressure gradually and consistently rather than squeezing with everything you have at the start—go 10%, 20%, 30% pressure until reaching 100%. This prevents giving your opponent a breather and allows you to hold the choke longer.
