BJJ vs Judo: Shared Roots, Different Rules
The clearest competition difference is what can end a match. In judo, a qualifying throw or pin can win outright. In BJJ under IBJJF rules, takedowns and ground control earn points, while a submission can finish the match immediately.IBJJF Rule Book (v6.0) [4]IJF Sport and Organisation Rules (SOR), Version 24 July 2026 [5]
Both arts include groundwork, strangles, and joint locks. They also share historical roots: Kodokan-trained Japanese practitioners helped shape the practice that developed into BJJ in Brazil.Modernization, Nationalism and the Elite: The Genesis of Brazilian Jiu-Jitsu, 1905-1920 [2]IBJJF Rule Book (v6.0) [4]Judo Techniques [6]
What the competition rules reward
This comparison uses the IJF Sport and Organisation Rules dated 24 July 2026 and the June 2024 rule-book asset linked by IBJJF. Consult the event’s division rules for the techniques and match conditions that apply to you.
| Action | BJJ: IBJJF rules | Judo: IJF rules |
|---|---|---|
| Throw or takedown | A qualifying takedown scores 2 points after the required control.[4] | A throw meeting the ippon criteria wins immediately. Lesser qualifying throws receive lower scores.[5] |
| Ground control | A guard pass scores 3; mount or back control scores 4 when the criteria are met. A pin has no countdown to victory.[4] | A qualifying pin scores yuko at 5–9 seconds, waza-ari at 10–19, and ippon at 20.[5] |
| Submission | A recognized physical or verbal submission ends the match.[4] | A recognized submission also wins the contest, scored as ippon.[5] |
| Combining scores | Points accumulate. If points are tied, advantages, penalties, and then referee decision decide the result.[4] | Two waza-ari make ippon. Yuko scores are counted separately and do not add up to waza-ari.[5] |
Both arts have ground techniques
The IJF technique catalog includes osaekomi-waza (holds), shime-waza (strangles), and kansetsu-waza (joint locks). BJJ also uses positional control, chokes, and joint locks.IBJJF Rule Book (v6.0) [4]Judo Techniques [6]
The scoring makes a practical difference: holding a qualifying judo pin long enough can end the contest, while an IBJJF BJJ match can continue after points for a pass or mount.IBJJF Rule Book (v6.0) [4]IJF Sport and Organisation Rules (SOR), Version 24 July 2026 [5]
A familiar-looking technique can have different legal limits across sports, ages, and divisions. Learn the rules of the class or event you are joining.
Choosing where to train
Visit the classes available to you. Compare the instruction, supervision, schedule, and what you enjoy practicing. Ask how beginners learn to fall, work from standing, practice on the ground, and enter live rounds.
If you train both, learn each coach’s expectations and the event rules separately. Start with BJJ for beginners before your first BJJ class.
