What is ne-waza (groundwork)?
Ne-waza is judo's ground fighting: pins, armlocks and strangles. How it differs from standing judo and from BJJ.
Ne-waza (寝技) is judo's ground fighting — pins (osaekomi-waza), armlocks (kansetsu-waza) and strangles (shime-waza).

How does What is ne-waza (groundwork)? work?
After a throw that does not score ippon, the contest often continues on the ground. Unlike Brazilian jiu-jitsu, ground time in judo is short: as soon as there is no progress the referee calls matte and both judoka stand up. In the Netherlands locks and strangles are only allowed from the U15/U18 age categories; pins are taught to youth from the start.
ne-waza in Amsterdam dojos
Amsterdam clubs explicitly label blocks as ne-waza nights so you can choose with intent. ne-waza is rarely drilled in isolation here: coaches link it to the groundwork family, with slow uke drills before pace and theme randori. Parents know the name from pools; what they miss is the quiet before the throw — grip, angle, timing. After class ask which cue was central that week.
What ne-waza actually is
ne-waza belongs to the groundwork family. You study ne-waza as a group: shared principles, not one isolated trick. You learn the full chain: kumi-kata, kuzushi, entry, finish and partner ukemi. Without that chain ne-waza stays a trick on cooperative ukes. Pedagogically the line sits close to Kodokan teaching; competition variants follow IJF criteria for grip and landing. Dutch clubs map that onto JBN kyu programmes. Ask which variant your club teaches (classic versus modern grip) so you do not mix two systems. Film one slow-motion entry each week. Most progress in ne-waza lives in the first two seconds — foot angle, elbow height, pull direction — not in a spectacular mirror finish.
How to train ne-waza safely
Inside ne-waza, alternate two representative techniques per block so the difference becomes tangible. Safety for ne-waza: enough distance to the mat edge, an uke who knows the fall, and volume that drops when the group is tired. Children start with uchi-komi without full projection; only then nage-komi. Core mistake: Throwing everything into one favourite technique and ignoring the rest of ne-waza. Halve the pace and let your sensei coach only the entry until it is clean. Add power again only after three clean reps in a row. Partner agreements: switch left/right, switch who is tori each minute, and stop with a clear tap signal. ne-waza without communication is how injuries happen — not how belts are earned.
ne-waza in shiai and scoring
In shiai you pick from ne-waza based on grip and distance, not Instagram favourites. Referees judge force, control and landing surface. One clean ne-waza outweighs two half-hearted attempts. Also drill the exit: release dangerous grips after the throw. Amsterdam pools often reward quick, clean landings. Combine your own shiai video with club feedback; online glamour clips miss shido risks (passivity, illegal grips) that do get called in Noord-Holland halls. After each pool note: which setup led to ne-waza, which grip failed, which opponent ukemi was awkward. Those three lines accelerate your next class more than randomly training harder.
Exams and progression for ne-waza
Exams often ask for several examples from ne-waza; know the family similarities. On JBN kyu exams you show ne-waza inside a throw set plus ukemi. Higher belts demand cleaner kuzushi and left/right on a moving uke. At dan level kata matters; individual nage-waza stays coach-dependent. Checklist before exam night: grip, angle, foot placement, finish, uke communication — signed off by your sensei. Without that list, “I can do ne-waza” is not evidence. For children: do not schedule an exam in the same week as a heavy tournament. Recovery and sleep outweigh one extra training night of poor ne-waza reps.
Local choices around ne-waza
Amsterdam clubs explicitly label blocks as ne-waza nights so you can choose with intent. Use the dojo guide to find a club where ne-waza sits in the syllabus, not only as a show for parents. Calendar clinics that deepen this exact technique are gold. Then read knowledge pages on kuzushi, kumi-kata and ukemi — the building blocks under ne-waza. Sources below are federation- or institute-grade; we rewrite claims and never copy official sentences. If torn between clubs: visit two trials and watch how coaches correct ne-waza. That correction language predicts your learning curve better than website photos.
Practice block 1: ne-waza
Family card ne-waza for groundwork: write three example techniques, a shared principle, a typical fault per example, and a shiai situation. Reread before class. Goal is systems thinking, not name memorisation.
Practice block 2: ne-waza
Class strategy: on a ne-waza night prepare a question about the shared principle of groundwork. Steer explanation toward comparisons, not show throws.
Practice block 3: ne-waza
Exam reasoning for ne-waza: practise two contrast pairs aloud (why A yes, B no). Without reasoning, a pretty throw is insufficient proof of family understanding.
Practice block 4: ne-waza
Shiai audit: after pools note which members of ne-waza you actually used. Next week force a second family member in theme randori so groundwork does not shrink into one trick.
Practice block 5: ne-waza
Hall adaptation: narrow Centrum halls train ne-waza more in place; spacious Zuidoost halls allow more line movement. Ask which variant applies that night.
Practice block 6: ne-waza
Sources: Kodokan for classic groupings, IJF documents for contest variants, JBN for exam requirements. No verbatim copying; cites yes.
Practice block 7: ne-waza
Deepening case for ne-waza: describe a concrete Amsterdam class situation (youth or senior) where this concept went wrong, which cue the sensei gave, and how the next three sessions were adapted. Write at least eighty words in your log; without that case theory stays floating. Then attach a measurable drill (time, reps or checklist) that applies only to this concept.
Practice block 8: ne-waza
Check moment for ne-waza: have a partner quiz you with five open questions that cannot be answered yes/no. Note gaps. Schedule a remedial drill within seven days. This check does not replace a federation exam but prevents discovering shaky definitions only on exam night.
Practice block 9: ne-waza
Integration with neighbouring concepts around ne-waza: pick two knowledge pages that logically sit beside it and write a paragraph on how they reinforce each other on the mat. Read that paragraph aloud to your sensei for correction. That builds a network of ideas instead of isolated lemmas.
Practice block 10: ne-waza
Quality bar for ne-waza: state when you are satisfied (for example three clean reps, a faultless etiquette sequence, or a clear parent explanation). Share that bar with your coach. Without your own bar, progress stays vague and you only compare yourself to others.
Examples
- Osaekomi-waza — hold-downs
- Kansetsu-waza — armlocks (seniors)
- Shime-waza — strangles (seniors)
