Judo in MMA

Sure, as an experienced Judo practitioner it is completely easy to throw some random person out on the street who has no grappling experience (newsflash: you’d probably be able to do it within your first few Judo classes). It is also relatively easy to throw a Judo beginner or someone with an intermediate or lower level of other grappling Martial Arts, once they’ve finally decked themselves out in a starchy brand new Gi for the first few times and are just getting used to break-falling. However, it takes years to be able to pull-off a clean Judo throw against a resisting and experienced opponent, even if they’re wearing a Gi and competing under Judo rules. Against a fully-resisting, grappling-experienced, striking-empowered, aggressive, not to mention barely clothed and sweaty opponent? It’s damn near impossible. So remember that next time you are watching any combat sport like MMA or grappling events like Metamoris / ADCC and say “why doesn’t he just throw him on his head and win already” or “I thought he does Judo, so much for that being effective”.

The problem with many Judo techniques in the context of MMA is that if you commit completely to the technique (which you often have to for an effective throw) but the opponent somehow manages to resist then you are typically in a very bad situation where your back, neck and/or head are completely exposed; or, you are otherwise off-balance and can be countered or taken down hard & painfully yourself with low center-of-gravity wrestling techniques. With this level of risk, its no wonder only a select few are able to pull off Judo techniques with any amount of consistency or grace when competing at the highest levels. That said, it does happen. So long story short, what are the highest percentage techniques to attempt in the MMA ring/cage?

The Top 10 Judo throws most commonly pulled off in MMA include:

  1. Osoto Gari
  2. Sumi Gaeshi / Hikikomi Gaeshi
  3. Kosoto Gake
  4. Kata Guruma
  5. Harai Goshi
  6. Uchi Mata
  7. Drop Seoi Nage variations
  8. Ouchi Gari
  9. Kouchi Gake
  10. Harai Tsurikomi Ashi / Hiza Guruma


1. Osoto Gari

Large Outside Trip

2. Sumi Gaeshi / Hikikomi Gaeshi

Corner Reversal & Pulling-In Reversal are two common sacrifice throws, especially since they can be done easily without a gi. The grip simply needs to be modified to over and underhook an arm or body lock from over-the-top. The legs use either the front of a bent leg (softly kicking/springing type of motion) from head-on for Sumi Gaeshi or outside of the leg (hip-hinging type of motion) from an angle, from having your back taken, or from a rotated position at 45 degrees for Hikikomi Gaeshi. The nice thing about this throw is that it isn’t that high impact so isn’t likely to hurt your opponent too much, it easily puts you in top-position on the ground without a battle, and if it fails for some reason, you can pull guard, slide to a leg-lock or even technically stand back up safely.

10. Harai Tsurikomi Ashi / Hiza Guruma

Lifting Pulling Ankle Sweep / Knee Wheel
Both the Harai & Sasae Tsurikomi Ashi (forward-lifting-ankle-block & backward-pulling-ankle-sweep) variations, as well as Hiza Guruma’s “knee wheel” separate throw mechanics all look very similar to the untrained eye. These are popular because they can be done from many different grips, including 2-on-1, over-under, body-lock, double-overhooks, wrestler’s tie-up, Thai clinch, etc…

In fact, here’s one of the few throwing techniques from traditional Muay Thai which looks just like Hiza Guruma:

As you can see there are only so many ways to throw a person or take them down to the ground, many Martial Arts have commonalities and unique interpretations. There are many downsides to MMA competition including a “tough-guy/thug” culture it can potentially breed, along with the risks of permanent injury (especially in light of recent evidence of the effect of cumulative head trauma contributing to long-term negative effects on the brain, something always expected but only recently measurable by scientists). However, certainly sanctioned bouts in a ring with a referee are preferable to senseless violence in the streets, if certain people were going to be fighting anyway it might as well be regulated and overseen for some amount of safety. There are also some benefits to the Martial Arts community for getting to see the best practitioners from separate disciplines face each other safely, under a reasonable rule set, to see how techniques compare.

&What is Kosen Judo?

Kosen Judo (高專柔道) is one of two main approaches to Judo training and competition (the other being Kodokan Judo) which are taught within Japan, the birthplace of that martial art and sport. Today, Kodokan Judo is by far the most dominant in terms of the number of clubs, instructors, students and competitions worldwide. While Kodokan Judo competition rules are recognized globally as the standard by the International Judo Federation (IJF) and are used for all Olympics and Worlds Judo competition, Kosen Judo is by contrast rarely heard of outside of Japan where it is still used during inter-University competitions (高專大会 kōsen taikai). Several organizations abroad such as the Freestyle Judo Alliance in North America, International Brazilian Jiu Jitsu Foundation (IBJJF) in South America and the European Sambo Federation, have adopted similar competition rules based on a combination of the more permissive ground fighting Kosen Judo rule set, blended to some degree with the stricter Olympic/Kodokan Judo rule set (some being even more permissive to allow striking, others adhering closer to Judo principles of using only throws and holds). Unlike Sambo or Brazilian Jiu Jitsu (BJJ) though, Kosen Judo is neither a different Martial Arts “style” nor is it simply a set of competition rules; rather, it is a spirit of preservation of Judo and Jiu-Jitsu traditions within the modernized sport-focused Judo community. Kosen Judo arose with this aim during the Meiji Era (1868–1914).

Development of Kosen and Kodokan Judo

Kodokan Judo was established primarily to turn dangerous yet effective techniques designed for the battlefield from traditional Jiu-Jitsu (which Samurai trained in for hand-to-hand fighting) and make them safer and more appealing to the general public (and thus, a broader array of potential students). Jiu-Jitsu was at the time, quite unfortunately, fading into obscurity as a relic of the old Samurai culture that was quickly being left behind by the Japanese public who seemed to be in favour of industrialization and modernization (not to mention the fact that it was being rendered much less important for the government due to ballistic advancements in military technology). Kodokan founder, the honorable Jigoro Kano, knew from his early studies in human anatomy, physiology/kinetics and anthropology that people are competitive by nature; yet he also observed when learning under Osteopath and Jiu-Jitsu master Hachinosuke Fukuda that people do not like to get hurt and injuries in a sport/activity often lead to abandonment of that sport/activity or outright inactivity. This lead him to develop a set of rules for safe competition, as well as a new school called the Kodokan Institute in 1882.

The departure from the traditional schools of thought on “fights to the death” and “survival (i.e. participation) of the fittest” which were so prevalent before the founding of the Kodokan, represents some key improvements Kano introduced. Like all new schools of thought though, there was initially stern condemnation of Kano’s approach and constant challenges from traditional Jiu-Jitsu masters within Japan. Despite this adversity, Kano’s own abilities, passion for teaching and unwavering dedication to his vision saw Judo rise in prominence across the country at the turn of the 20th century. It was becoming apparent that the only way many traditional Jiu-Jitsu techniques may survive would be to find a way to get included in the new “Kodokan curriculum” and “sport of Judo” being developed by Kano. As a result, followers of the old ways of Jiu-Jitsu had three choices: quit altogether, join him, or ignore him. A vast majority of those who chose to “ignore him” could at least agree that he had a brilliant idea to make Martial studies more appealing to the masses, and attempted to develop their own streams of sport Jiu-Jitsu (their own “Judo”, in essence).

History of the Musa Betsu Kyu Judo club

Sensei Earl O’Blenis is a longtime Judo teacher and longer-time Judoka (Judo competitor). As an instructor, he is certified with Judo Canada and also sits on the board of directors of the Province of New Brunswick’s official Judo affiliate and regulatory body, Judo NB as the Director, Moncton Zone.

He began training in Judo at the age of 19 and has spent the past 15 years teaching Judo in the Greater Moncton area.



As a competitor, his tournament history includes participation and wins in elite-level Judo tournaments on the Provincial (NB & NS cups), National and International scales. As a coach, he has also mentored students to wins in over 200 tournaments during his 15-year coaching history.



Initially, the club practiced out of Wynwood School (1998-2006) next to the old Kay Arena. When the school was torn down to make way for the current Crossman Community Center and Kay Arena complex, classes were relocated to the Moncton Lions’ Center (2006-2008). From 2009 to present, the home of the Musa Betsu Kyu Judo club has been the new Kay Arena building on Mondays and Thursday nights, as well as the NBCC/CCNB Dieppe campus, which has held classes on just about every Tuesday night since 2003 (except when special NBCC/CCNB school events such as the annual booksales or Tree-Of-Hope prohibit).

Official Judo rules

What are the official Judo rules?

This is a common question amongst students, and up until recently, the answer has been “I don’t know, it changes every other year!” (see: history of Judo rules)
Well the International Judo Federation (IJF) has finally agreed on competition rules for the next three years forward so we now know that at the very least, starting from January 1st, 2014 until December 31st, 2016 we will have the same set of rules for Judo competitions.

Here’s the abberviated (or “Coles Notes”) summary of the rules for quick reference, while the new full rules follow below:
