Overview

Hadaka-Jime is applied without using the judogi — tori's forearm wraps directly around uke's neck. Known widely as the "rear naked choke" in MMA and submission grappling, it is highly effective because it does not depend on gripping the jacket. Applied from behind, the forearm compresses the carotid arteries. It is the most widely recognized submission hold in all combat sports.

How to Execute

Hadaka-Jime — Step by Step

  1. 1

    Establish back control

    Get behind uke with your chest against their back. Hook your legs around uke's hips to maintain the position.

  2. 2

    Slide your right arm across uke's throat

    Wrap your right arm around uke's neck so the crook of your elbow aligns with the center of their throat. Your forearm slides across to their right carotid.

  3. 3

    Place your left hand behind your right bicep

    Reach your left hand over uke's left shoulder and grip your own right bicep to form the figure-four: your right arm is across the throat, your left hand squeezes the right bicep, and your right hand rests on your own left shoulder or the back of uke's head.

  4. 4

    Place your left hand behind uke's head

    Push uke's head forward with your left hand. This tightens the choke by removing their ability to pull their chin down.

  5. 5

    Squeeze both arms and arch back

    Squeeze your arms together to compress both carotids. Arch your back to intensify the pressure. Both elements together create rapid carotid compression.

Key Principles

What Makes It Work

  • The crook of the elbow should be at the center of the throat (adam's apple area), not the forearm across the throat.
  • The figure-four grip (hand on bicep) amplifies pressure significantly over a simple wrist grip.
  • Pushing the head forward with the rear hand removes uke's ability to tuck their chin, which is the primary defense.
  • Arching away from uke stretches the neck and tightens the grip simultaneously.
Common Mistakes

What to Avoid

#1 Common Mistake

Forearm across the throat (windpipe) instead of carotid

The crook of the elbow — not the forearm — sits at the throat. The forearm and upper arm compress the carotids on both sides.

#2 Common Mistake

Not using the figure-four grip

Grip your bicep, not your wrist. The figure-four creates far more mechanical pressure.

#3 Common Mistake

Allowing uke to tuck their chin

Push their head forward with your rear hand to prevent chin tuck. Once uke tucks the chin, the choke is partially blocked.

When to Use

Best Moments to Apply Hadaka-Jime

Hadaka-Jime is the primary option whenever you have back control. If uke's collar is accessible, Okuri-Eri-Jime is an equally strong choice — both should be drilled as co-primary options from the back position. Extremely effective when uke is turtled and you have hooks in, or when no gi collar is available.

FAQ

Frequently Asked Questions

Is Hadaka-Jime the same as the rear naked choke in MMA?
Yes — the mechanics are identical. The judo term is Hadaka-Jime (naked choke, meaning without the gi). In MMA and BJJ it is widely called the Rear Naked Choke (RNC). It is one of the most finished submissions in all grappling sports.
What is the difference between Hadaka-Jime and Okuri-Eri-Jime?
Hadaka-Jime uses a direct forearm wrap around the neck without using the gi. Okuri-Eri-Jime uses the lapel/collar of the judogi as part of the choke mechanism. Hadaka-Jime is available even without a gi.
What belt level is Hadaka-Jime?
Shime-waza are typically introduced at 3rd kyu (green belt) in standard judo curricula.
