Kata Juji Jime
Genus片十字絞(Kata Juji Jime)
TraditionalTranslation: half cross strangle
Overview
Kata Juji Jime is the half cross strangle — one hand grips the lapel palm-down while the other grips palm-up, creating an asymmetric cross choke that attacks from a slightly different angle than the normal version. [1] The mixed grip (one palm up, one palm down) creates a different pressure vector that can be harder to defend against. [1] One of the three Kodokan cross strangles. [1]

Biomechanical Mechanism
Primary Action — One hand grips palm-down, other palm-up, forearms cross to create asymmetric choking pressure
Joints Involved — Both wrists (mixed grip), forearms (crossing pressure), shoulders
Force Vector — Asymmetric compression — the mixed grip attacks the neck from slightly different angles
Target — Carotid arteries — blood choke
Position & Entry
From mount — One hand palm-down in the collar, other palm-up, cross and squeeze
When Nami fails — Switch one hand to palm-up for different angle of attack
Variants
Strong side emphasis — more pressure on the palm-down side
Weak side emphasis — more pressure on the palm-up side

What Instructors Say
Kata Juji Jime is a cross-collar choke variation taught primarily from guard position, distinguished from standard Juji Jime by its application when the opponent prevents insertion of the second hand. Peter Mettler Martial Arts demonstrates the technique across two contexts: from full guard and from side mount (where it becomes the "paper cutter choke"). In both positions, the core mechanics remain consistent: one hand is inserted deep into the collar with four fingers, positioning the wrist below the earlobe where the sternocleidomastoideus and carotid artery are located. The distinguishing feature of Kata Juji Jime is the use of a reaching grip around the opponent's trap or shoulder fabric with the second hand when direct collar access is blocked, rather than forcing a second collar grip. The choke is executed through body weight and leverage rather than isolated hand strength, with the operative forearm (the "blade"—the radius side) cutting into the neck via a rotating, lifting motion. Frame control with one elbow while the opposite forearm applies pressure is critical. The technique's advantage lies in maintaining closed guard position without compromising posture or structure while still achieving a submission, making it suitable for both gi jiu-jitsu and MMA applications.

Unified Rules of MMA, August 2025PDFTraining Notes
✓The palm-up hand must grip DEEP — it provides the anchor for the choke
✓The palm-down hand drives the choke — pull this elbow aggressively
✓The mixed grip creates a different pressure vector than Nami — experiment to find which angle works best for your body
✓Can be set up when one grip is already established from a different technique
Common Mistakes
!Both hands same orientation — that's Nami or Gyaku, not Kata
!Shallow grip on the palm-up hand — loses the anchor
!Not pulling elbows together — the cross must be tight
!Confusing which hand goes where — practice until it's automatic

Kata juji jime (half cross strangle) uses one hand palm-up and one hand palm-down on the opponent's lapels. The asymmetric grip creates a different pressure angle than nami or gyaku juji jime. (Kano, Kodokan Judo)
Frequently Asked Questions
Where should my wrist be positioned when entering the kata juji jime?
Your wrist should be positioned directly below the opponent's earlobe, where the sternocleidomastoideus muscle is located. This positioning allows you to apply pressure to the carotid artery for an effective choke.
How do I prevent my opponent from escaping by framing my elbow?
Keep your elbow positioned lower than your wrist and frame your opponent's chin with your forearm. This makes it difficult for them to push against or frame your elbow, while also preventing the arm-under escape.
Should I use my triceps to apply the choke or is there a better method?
Rather than extending your forearm with tricep strength, hang onto the collar and use your body weight by leaning into your elbow. You can also pull on the collar to add additional weight and force to the choke.
What's the key difference between juji jime and kata juji jime?
Kata juji jime is used when you cannot enter your second hand for a traditional juji jime. Instead, you frame the opponent's leg with one elbow while using your blade (forearm) to cut and compress the neck through a rotating motion.
How does the Kata Juji Jime work?
Kata Juji Jime is the half cross strangle — one hand grips the lapel palm-down while the other grips palm-up, creating an asymmetric cross choke that attacks from a slightly different angle than the normal version. The mixed grip (one palm up, one palm down) creates a different pressure vector that can be harder to defend against.
