Short Answer

Key Takeaways

Pause to identify which fingers enter each collar before naming the technique.
Compare whether both hands match or form a mixed grip.
If a grip is hidden, note a question for your instructor rather than infer it from camera position.

The clip title joins three names. Pause each section to identify the grip, especially when one hand is hidden. Camera-relative palm direction alone can mislead.

In this article

What the name tells us

The official names are 逆十字絞 (gyaku-juji-jime), 片十字絞 (kata-juji-jime) and 並十字絞 (nami-juji-jime). Juji refers to crossing, while the first words distinguish grip forms.

How the technique works

Kodokan describes four fingers inside both collars for Gyaku, thumbs inside both for Nami, and one of each for Kata. These are identification points for viewing, not instructions to experiment with strangle pressure independently.

This single article compares three crossed-collar grips. In Kodokan's definitions, gyaku-juji-jime puts both sets of four fingers inside the collars, nami-juji-jime puts both thumbs inside, and kata-juji-jime combines the two orientations. Inspect the actual hands; the camera angle can obscure palm orientation.

What to watch in the clips

Pause to identify which fingers enter each collar before naming the technique.
Compare whether both hands match or form a mixed grip.
If a grip is hidden, note a question for your instructor rather than infer it from camera position.

A distinction worth noticing

Do not confuse Juji Jime with Juji Gatame. Both use juji in the name, but the former belongs to strangles and the latter article concerns a joint technique. Gyaku-Kata-Nami is a grouped label, not one official technique name.

Kata does not mean using only one hand, and gyaku does not mean starting behind the partner. All three are front-applied juji-jime forms. Compare hand and collar orientation rather than ranking which produces greater pressure.

Taking the lesson back to practice

Review names and grip forms with an instructor without applying strangle pressure. The instructor decides readiness and practice conditions. Agree on stopping signals and release immediately; unconsciousness or endurance is never the practice target.

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 pressure and identify each grip separately. If the fingers are hidden, record that uncertainty and ask your instructor instead of guessing from the torso pose. This comparison teaches names and structure, not experimentation with neck pressure until symptoms occur.
