Hadaka-Jime: The Core Technique for Practical Unarmed Combat

This is an interesting book and an interesting approach to training. The approach makes a great deal of sense to me in focusing on a single technique, with multiple ways of getting into this technique.That said, the technique, hadaka jime, as described in the book, is quite dangerous. The way the technique is presented in the book is not the way it's typically implemented in competition.The technique in the book is a potentially lethal variation of the rear naked choke that is used in judo and jiu jitsu competitions. As presented in the book, the pressure across the windpipe and the upward pressure on the rear of the skull, expanding the vertebrae in the neck of the opponent, is extremely dangerous to a training partner. The leverage that can be obtained by using the shoulder on the back of the skull and against the vertebrae in the neck while simultaneously using the opposite forearm as a lever in the opponent's upper back (which is how the technique is described in the book) is substantial.As done in competition, the technique is usually implemented as a blood choke at a very different angle than as presented in the book (going against the sides of the neck rather than the front and back, with little or no pressure against the vertebrae in the neck). If held for only a brief time, a blood choke can safely put a person to sleep (if held for a long period of time though, this variation is also quite dangerous).Granted, the book is showing the technique in a military context, where lethal techniques make sense. But anyone practicing this technique should be very aware of how dangerous it can really be. Great caution should be exercised in practicing the technique as presented in the book.Please be careful! Seek out a qualified instructor.

This compact work by Moshe Feldenkrais, concerns a method of Combat Judo based on ONE primary technique [Hadaka-Jime] -- or rather an older combative variant of the so-called "Naked Choke". This [dangerous] combative variant uses forearm leverage mostly across the foe's windpipe and additional great crushing-pressure on the foe's rear neck -- to increase total lock-pressure on the foe's windpipe-and-neck and to thereby most firmly control foe and avoid position give-away noise-and-struggle. The Modern Judo variant using lateral neck "nut-cracker" pressure to block brain blood flow -- is [theoretically] quicker -- likely under a minute, rather than over a minute for the combative variant of this book, to render a foe helpless. But, for grim [mortal] combat purpose, the variant used in this whole book, is one of the best techniques that can be used by combatants in many situations to counter many threats via many lead-ins to the Hadaka-Jime chosen by Moshe Feldenkrais -- who was concerned to present a most compact unified method that could be learned quickly and retained long by combatants of Great Britain in WW II. For those that prefer the Modern Judo variant of Hadaka-Jime -- well, this fine manual does show various ways to smoothly lead into a "Naked Choke" -- of whatever type -- especially for combative [especially Commando CQC] self-defense. In any case, this manual is a Fine Gem of a work -- showing just what is possible and practical for most compact combative self-defense -- with clues and cues given for general body-and-mind co-ordination and integration +++

I found this book fascinating, not so much for its content as for the training concept that lies behind it. Dr. Feldenkrais took a single technique (hadaka jime or rear naked choke) and built a system of unarmed combat around it.I don't think the book's content has much value in self defense from a standpoint of liability. Crushing an opponent's airway as the first and only option might undermine someone's plea of self defense in the courtroom. HOWEVER, the structure and outline of the material could serve as a template for a self defense short course based on a single technique.

It is exactly what the title says. Many different ways to perform a single technique, hadaka jime, or the rear naked choke. It is NOT about that one "killer move" that will always work and make you invincible. There isn't one. While the book details the ways a highly qualified instructor taught the technique to beginners, this is probably not a book for beginners to learn from by themselves. There is a lot of potential for "mislearning" and injury from reading this book that while explained well, are not made visceral under the supervision of an experienced judoka or jujisuka.For an instructor or practitioner experienced with some hadaka jime experience, this is an excellent resource. It is a great comprehensive reference on execution of hadak jime from a variety of situations. It not only provides detailed instructions on many of its own entries it creates a thought process that allows for even more creativity with the technique's implementation. The asides on Dr Feldenkrais' biography and history make it a fun as well as highly instructional read. I thoroughly enjoyed it.

Super little booklet describing the deadly use and simple application of Hadaka Jime (naked choke) from one of histories most interesting martial arts practitioners. Written for the British Army during WW2 it provides the reader with several applications of the technique, geared towards hand to hand fighting, and demonstrates the quick lethal disposal of a soldiers opponent in battle. Contains excellent pictures and clear notes.Short and concise. A must have for any martial artist especially for Judo and Jujitsu.

Well written study from the 1940s describing its title.

Great book...straight forward and to the point.
