Sambo vs Judo vs Jujitsu: What Actually Differs, Read From the Rulebooks

All three belong to the same family: arts that use clothing as a tool. You grip, you pull, you break the balance, and you finish with a throw, a hold or a joint lock. To an outsider the picture looks close enough that the three read as one art under three names.

Open the rulebooks, though, and the difference is not in the techniques, because many of the same throws exist in all three. The difference is in what each rulebook allows, what it forbids, and what ends a match. Those rules are what shape how people train and how they think over the years.

This article compares the three sides using documents from the International SAMBO Federation, the International Judo Federation, the Ju-Jitsu International Federation and the IBJJF rule book, which is the set most competitors meet in Brazilian jiu-jitsu.

Jujitsu is the oldest of the three, and it is not a single art. On its history page JJIF names older schools such as Takenouchi Ryu, dated to 1532, along with Kito Ryu and Yoshin Ryu, and says Kito Ryu strongly influenced Kodokan judo. There is more on the JJIF sport pages and in our article on judo and jujitsu in Japan.

Judo has a much sharper starting point: Kano Jigoro established the Kodokan in 1882 and rebuilt training and competition out of those older schools. The full story is in our article on what judo is. Judo entered the Olympic programme in Tokyo in 1964, and both men and women have competed since Barcelona in 1992.

Sambo was born in the Soviet Union and is the youngest of the three. The FIAS history page names three key figures, V.S. Oschepkov, V.A. Spiridonov and A.A. Harlampiev. The name comes from the Russian самозащита без оружия, self-defence without weapons. FIAS treats 16 November 1938 as the sport's official birth date, and says the present name came into use in 1947.

Internationally, FIAS was founded at a general assembly in Madrid on 13 June 1984. The International Olympic Committee granted provisional recognition on 30 November 2018 and full recognition in 2021, as stated on the FIAS about page. Recognition is not inclusion, though: sambo is still not on the Olympic programme. Thailand has a national body listed by FIAS as the Sambo Association in Thailand.

This table compares sport sambo, judo under IJF rules, and Brazilian jiu-jitsu under IBJJF rules, because those are the three sets a competitor in Thailand is most likely to meet. Combat sambo is handled separately in the next section.

Read down the table and it becomes clear why crossing over feels uncomfortable. A judoka entering sambo has to protect their own legs in a way they never had to before, and a sambist entering judo has to give up an entire category of finishes.

The FIAS about page lists three competition disciplines: sport sambo, combat sambo and beach sambo. When somebody says sambo has punches and kicks, they mean combat sambo specifically, not sambo as a whole. The detail sits in the FIAS rules and documents.

In sport sambo the rules allow painful holds on the arms or the legs until the opponent submits, but chokeholds sit on the prohibited list, as does direct impact on the face with hands, feet or head. The combat sambo rules say the opposite: chokeholds are permitted both standing and on the ground, and kicks are allowed with any part of the foot. That is why practitioners of the two branches train very differently while using the same name for their art.

Both rulebooks agree on one class of prohibition, the twisting attacks: the foot knot and the knee lever applied outside the natural plane of the joint are forbidden in each. The other giveaway is visible from across the hall, because sambo is competed in shoes, unlike judo and jujitsu, which are competed barefoot.

IMAC Dojo does not run a separate sambo class. Combat sambo principles are used in the clinch and throwing ranges of the Wing Chun Sambo course, which keeps Wing Chun as its close-range core.

The IJF rules state plainly that joint locks are allowed on the elbow only, and that locking any other joint is hansoku-make, an immediate loss. The source sits in the IJF documents. That is the straightforward reason many judoka never train a defence against a leg lock across an entire competitive career.

The other frequent question is leg grabbing. The current IJF rules penalise hooking the leg with the hand or arm, and gripping the trousers, with shido. They also state that gripping under the belt down to the top of the inner thigh is allowed, and that gripping the leg is permitted once both athletes are clearly in a ne-waza situation. The restriction dates from the early 2010s, but I do not name a specific year here, because I could not find an IJF page that states one directly.

In the other direction, judo permits what sport sambo does not: the choke. Chokes and elbow locks are available at senior level and are kept out of the under-16 categories on safety grounds. For a sense of how far one rulebook can still be applied differently from country to country, read our article on judo competition rules in Japan and Thailand, and the class details are on the IMAC Dojo judo course page.

Jujitsu is a collective name for many separate Japanese schools of unarmed combat, not a single art with a single rulebook. JJIF itself says it does not represent one particular style but draws on the knowledge of several. Today JJIF runs several competition formats, including the Fighting System, Ne-Waza, the Duo System, the Show System, Contact Ju-Jitsu and Para Ju-Jitsu, and they look different enough that a spectator might not place them as one sport.

Brazilian jiu-jitsu, meanwhile, grew out of the Kodokan judo that was taught in Brazil in the early twentieth century, most often credited to Mitsuyo Maeda, who arrived there in 1914. The story of the Gracie family's training with Maeda is preserved mainly in family accounts rather than in federation records, so I write only what can be checked, and I do not state how many years anyone trained with anyone.

In today's competition the IBJJF rules contain no striking at all, and list punches, elbows, knees, head butts and kicks as disciplinary offences. Heel hooks and knee reaping, once illegal across the board, are now permitted for adult brown and black belts in the no-gi divisions, a change effective from 1 January 2021. The detail is in the IBJJF rules.

It depends on the goal. If you want safe falling, balance breaking and throwing inside a system with a clear competitive path from childhood, judo answers that best. If you want to spend long stretches on the ground and solve problems with submissions, Brazilian jiu-jitsu is the most direct route. Sambo sits between them: judo-like throwing with far more room for leg attacks, and the combat branch adds striking on top of that.

If the goal is everyday self-defense, the useful question is not which art hits harder but whether the curriculum covers the ranges you would actually meet. A real situation starts at distance, passes through the clinch, and only then reaches the ground. An art that is excellent at one range alone always leaves a gap, and no art removes the risk by itself.

At IMAC Dojo judo runs as a course of its own, while sambo and jujitsu are not taught as separate classes: their principles are used in the throwing and ground ranges of the Wing Chun Sambo course. Students who already train judo or jujitsu and want to add distance and striking are the group this course answers most directly.
