Do Jime
SubFamily胴絞(Do Jime)
TraditionalTranslation: body scissors strangle
Overview
Do Jime is a body scissors technique where the attacker wraps their legs around the opponent's torso and squeezes, compressing the ribcage and diaphragm. [1] It restricts breathing and can cause significant pain to the floating ribs. [1] Do Jime is one of the four kinshi waza (prohibited techniques) in IJF judo competition due to the risk of rib fractures and organ compression, but it remains legal in sambo and MMA. [1]

History & Origin
Do Jime is one of four kinshi waza (prohibited techniques) in Kodokan judo, along with Kani Basami, Kawazu Gake, and Ashi Garami. [1] It was banned due to the risk of rib fractures and organ compression. Despite the judo ban, body scissors and body triangles remain fundamental control tools in BJJ, sambo, and MMA. [1]
Effectiveness
Extremely effective as both a submission and a control tool. [1] The compression of the floating ribs causes intense pain and restricts breathing. In MMA, the body triangle (a legal variation) is one of the most dominant back control positions. Banned in judo specifically because of the injury risk to ribs and internal organs. [1]
Lineage
Kodokan judo lineage: Jigoro Kano (1860–1938) systematized this technique as part of the Kodokan judo curriculum. Transmitted through the Kodokan instructor system to judo federations worldwide. Adopted into BJJ through Mitsuyo Maeda → Carlos Gracie → the Gracie family lineage. [1]
Competition Record
Recognized Kodokan judo technique. Used in IJF World Championships and Olympic judo competition. Frequency varies by weight class and era. [1]

Target — Floating ribs, diaphragm, liver/spleen
Position & Entry
From guard — Wrap legs around opponent's midsection, lock ankles, squeeze
From back control — Wrap legs around the torso from behind instead of hooking inside

✓BANNED in IJF judo — do not use in judo competition
✓Legal in sambo, MMA, and most grappling rulesets
✓The squeeze must be with the LEGS, not just ankle lock pressure
✓Focus on compressing the floating ribs — these flex and cause extreme pain
✓Release immediately if your training partner taps — rib injuries are serious
Common Mistakes
!Using in judo competition — this is a kinshi waza (prohibited technique)
!Squeezing only with ankles — must use the entire leg
!Positioning too high (chest) or too low (hips) — target the floating ribs
!Holding too long when the opponent taps — rib fractures can occur quickly

Notes
Do jime (trunk squeeze) is a judo technique banned in IJF competition — it uses the legs to scissor-squeeze the opponent's torso. Classified as a prohibited act under IJF rules due to the risk of rib fracture and internal organ damage. Still practiced in kata. (Kano, Kodokan Judo; IJF Sport and Organisation Rules 2025)
Frequently Asked Questions
How do I position the cloth/gi on the neck to make do jime effective?
You need to get the cloth positioned on the artery rather than the windpipe. Place it over the base of the neck to avoid a neck crank, and use a soft, subtle approach when initially setting it up so your opponent doesn't sense the strangle coming and defend aggressively.
What's the most common mistake people make when setting up do jime?
People tend to attack the strangle too aggressively or at the wrong angles—hitting the windpipe, jaw, or front of the throat instead of targeting the artery. Instead, slip the cloth in gently and subtly, then rely on hip movement and body weight to finish the choke rather than hand pressure.
How should I use my legs and hips when executing do jime?
Your pivot and leg positioning create tension to give your hips something to move against. After slipping into position, sit down and spin into your opponent, using your body weight and hip motion (whether a drop back or drop in) to complete the strangle rather than relying on arm strength.
