Judogi — the judo uniform explained
What is a judogi, which sizes and weights exist, and how a beginner gi differs from competition gear.
A judogi is the white or blue cotton uniform with thick lapels used for gripping.

A judogi is the white or blue cotton uniform with thick lapels used for gripping.
How does Judogi — the judo uniform explained work?
The gi must survive grips and washing. Beginners use light student gis (under 500 g/m²); competitors need IJF-approved gis from about 700 g/m². Size by height; cotton shrinks — allow one size margin.
judogi in Amsterdam dojos
In Amsterdam dojos judogi shows up as gi sizing, lapel thickness and belt. Coaches explain it with IJF approved versus club gi, and mainly correct buying too loose or too short. This page translates official frames (JBN/IJF/Kodokan where relevant) into class practice without lifting federation prose.
Meaning of judogi
judogi centres on gi sizing, lapel thickness and belt. Concretely on the mat: IJF approved versus club gi. The idea is not separate from ukemi, gripping and respect — knowing only the definition misses how coaches place it in the syllabus. Historically and institutionally we point to Kodokan and/or IJF frames; for Dutch exams JBN leads. We summarise in our own words. After class write one sentence: which cue did you hear for judogi? That sentence is homework — not a random YouTube compilation.
judogi in the weekly class
A typical Amsterdam class builds judogi in layers: short briefing, slow partner drill, pace, then apply in randori or an exam-like demo. Centrum groups have less running space; Zuidoost more often has longer lines — teaching adapts to the hall. For youth, repetition with game forms matters; for seniors, transfer into shiai or kata. Ask your sensei which block touches judogi that week. Parents: stay sideline, do not photograph randori without permission, and discuss judogi positively — mistakes belong to learning.
Competition, exams or etiquette around judogi
Depending on the concept, judogi touches shiai rules, kyu/dan requirements or etiquette. Check current IJF documents for scoring/penalties and JBN for graduations. Noord-Holland clubs translate that into pools and exam evenings on this site’s calendar. Separate ‘what is legal in contest’ from ‘what we practise in class’. Class intensity can be lower to learn judogi safely. When unsure, the newest official source plus your sensei wins — not a forum thread.
Safety and misconceptions about judogi
The biggest risk around judogi is buying too loose or too short. Say that aloud before you train harder. Safety is part of the concept, not an appendix. Misconception: that judogi arrives ‘by itself’ after enough videos. Without feedback from a qualified coach you groove errors. Second misconception: that every child needs the same pace. Injury or fear? Cut volume and rebuild from ukemi and basic gripping before judogi returns at full speed.
Choosing and deepening judogi in Amsterdam
Use the dojo guide to find a club where judogi sits seriously in the programme. Pair with calendar clinics and related knowledge pages. Sources below support claims; we do not copy them verbatim. Trial checklist: how they explain judogi, how they correct, how safe the mat feels. Two trials beat ten landing pages. Keep returning to gi sizing, lapel thickness and belt — that is the through-line, not scoreboard stress.
Practice block 1: judogi
Week plan judogi (gi choice): class 1 isolates sizing/lapels; class 2 applies judogi in a theme drill; class 3 you observe others and write three cues. Sunday: five-sentence reflection — no video binge.
Practice block 2: judogi
Sensei talk on judogi: one question on gi choice and one on how sizing/lapels fits your age/belt. Write answers verbatim as a monthly checklist.
Practice block 3: judogi
Risk card for judogi: failure scenarios plus countermeasures, shared with a fixed partner. Update after near-misses. Safety is part of the concept.
Practice block 4: judogi
City guide: find an Amsterdam club/clinic that names judogi explicitly, bring a notebook, compare cues to your club. Facts rest on sources below; feel comes from the mat.
Practice block 5: judogi
Misconceptions: video alone does not make judogi; every child has a different pace; scoreboard stress is not pedagogy. Replace those myths with one measurable drill per week.
Practice block 6: judogi
Source hygiene for judogi: pick JBN/IJF/Kodokan by relevance, rewrite claims, on conflict the newest official page plus your sensei wins. No copy-paste of federation prose.
Practice block 7: judogi
Deepening case for judogi: 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: judogi
Check moment for judogi: 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: judogi
Integration with neighbouring concepts around judogi: 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: judogi
Quality bar for judogi: 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.
Practice block 11: judogi
Closing depth judogi (Amsterdam): tie this concept to a fixed moment in the weekly class — briefing, drill or randori — and protect that moment from ad-hoc tournament prep. Write a twelve-sentence letter to your future self about what you want to improve in three months around this exact concept, including ukemi limits, grip agreements and how you ask for feedback. Reread the letter monthly. Add a five-item yes/no checklist that applies only to judogi, have your sensei initial it, and keep it with your judogi. That moves the lemma from "read on a website" to "drilled behaviour".
Practice block 12: judogi
Second closing block judogi: run a fifteen-minute mini-clinic with two partners where you teach what you understand so far. Teaching exposes gaps faster than following. Note three questions you could not answer and schedule within ten days a look at the official sources at the bottom of this page plus a club question. End with a safe cool-down matching the load of judogi — no bonus throws after fatigue.
Examples
- Student gi — first two years
- Competition gi — official matches
- Blue gi — some senior competitions
