The judo blue belt is usually the 2nd kyu. By now you have a real repertoire standing and on the ground, and the typical syllabus adds counters, strangles and a personal attacking system. It's often the grade where competition training gets serious. As with every colored belt, your coach and federation set the content, so this is what is usually expected rather than an official list.
Why the judo blue belt changes things
At blue belt, the question is no longer whether you know a technique. It's whether you can land it against someone who doesn't want to fall. That's a huge difference. Plenty of green belts know uchi-mata. Few make it work in a real fight.
It's also the grade where randori partners get tougher. The club's brown and black belts stop holding back and throw you for real. If you no longer feel them going easy, that's a good sign: they now see you as an opponent.
What gets added to the syllabus
Lists change from one dojo to the next. These blocks come up often, taken from the later groups of the gokyo.
Standing: hane-goshi (spring hip throw), ko-soto-gake (minor outer hook), ashi-guruma (leg wheel), and a side sacrifice such as sumi-gaeshi. Sumi-gaeshi deserves attention. Against an opponent bent forward with stiff arms it's very effective, and many defensive competitors don't see it coming.
Counters enter the syllabus too. The principle is to use your partner's attack to throw them. Against a badly balanced o-soto-gari, you come back with o-soto-gari. Against harai-goshi, you lift with ura-nage or reap the supporting leg.
On the ground, teenagers and adults move on to strangles: hadaka-jime (naked strangle) and okuri-eri-jime (sliding collar strangle). Ne-waza stops being a place where you just survive. You start winning fights there. When these techniques are taught depends on the student's age and the rules of their category.
Blue belt and competition: the first real fights
Most blue belts have already competed. But this is often when they move from club events to open tournaments and official competitions in their age group.
A few things to master before you step on the mat:
- scores and penalties, explained in our guide to judo scoring: ippon, waza-ari and shido;
- your weight category, and how to manage it without crash dieting;
- golden score, the extension where the first score wins.
Categories and competition levels differ by age. Our page on judo competition levels walks through them.
One tip for every blue belt: log your fights. Who you fought, which technique scored, which attack beat you. A notebook works, and the Jutrack app does it in a few seconds. After ten fights you'll notice you often lose the same way, and you'll know what to train.
Kumikata becomes decisive
From blue belt on, most fights are decided on the grip. The player who gets their preferred grip attacks. The other one suffers. A blue belt should be able to take their grip quickly, break the opponent's without turning the fight into a hand battle, and attack within seconds of gripping.
So kumikata work takes a big share of training. Simple drills work well: randori where you can't let go of the sleeve, or one-minute exchanges where you must attack within three seconds of gripping.
Watch out for the opposite excess. The refereeing rules penalize passivity and certain grips, and a competitor who blocks without attacking collects shido fast. Kumikata exists to set up attacks, never to prevent the fight.
What the coach assesses at 2nd kyu
Coaches look less at the number of techniques and more at coherence. A blue belt should have:
- a main attack, landed on both sides if they're versatile, or at least in two directions;
- a combination that protects that attack once opponents know it;
- an automatic link from standing to the ground.
Behavior counts too. In most clubs, a competitor who argues with referees or injures training partners won't see brown belt soon.
The ground standards are real as well. A blue belt who gets rolled onto their back every time they're on all fours hasn't finished the job. Coaches expect at least a solid ground defense and one hold-down you can apply straight after a throw.
The pure competitor trap
Some blue belts think only about winning. They shrink their judo to two techniques and a blocking grip. That works in the cadet age group, then stops dead against more mobile opponents. Worse, it's poor preparation for black belt, which usually requires kata and clean technical demonstration.
Keep a slot in every session for "correct" judo without resistance, where you polish your off-balancing. The two feed each other.
Next on the path is the brown belt, the last kyu before black. To place blue in the full sequence, see our judo belt colors and order page. And if you also train BJJ, don't mix them up: the BJJ blue belt has neither the same rank nor the same timeline.
