Kumikata is gripping in judo: how you take hold of your opponent's judogi and how you stop them taking yours. People think judo is about throws, but most matches are decided by kumikata before anyone attacks. The player who gets their grip attacks. The one who loses it defends.
The standard grip
In a right-handed stance, your left hand holds uke's right sleeve at or just below the elbow. That's the hikite, the pulling hand. Your right hand holds uke's left lapel at chest or collarbone height. That's the tsurite, the lifting and steering hand.
The hikite grips tight with the last three fingers. The tsurite stays looser so it can push, pull or lift. Keep the tsurite elbow low, in front of uke's chest, to control distance and feel their movement.
Two beginner mistakes show up in every club. The first is squeezing with both hands, which burns out the forearms in two minutes. The second is locking the arms straight to block. Stiff arms protect you from an attack, but they also stop you from creating any off-balance (kuzushi).
Right vs left: ai-yotsu and kenka-yotsu
When two right-handers face each other, that's ai-yotsu. Lapels are on the same side, shoulders line up, and the fight looks like the one you practice every week. The battle is mostly over the lapel hand: who gets it higher and sooner.
Against a left-hander it's kenka-yotsu. The lapel hands cross and both players want the outside position. The first exchanges often happen on the sleeve. Whoever controls the sleeve of the other's lapel arm stops them from entering. In kenka-yotsu, attacks like uchi-mata or o-soto-gari come out more easily on the side of the lead hand.
Our take: right-handers don't train enough against lefties. Ask the left-hander in your club for a randori every week. If you are the left-hander, enjoy the natural edge.
How to win the grip fight
Grip fighting isn't about raw strength. A few principles that work:
- take the sleeve first, because it's harder to defend than the lapel;
- break a grip by turning the opponent's wrist toward their thumb, the weak point of any hold;
- grip while moving forward, never while backing up;
- attack within two seconds of getting your grip, before they break it.
The last point matters most. A perfect grip with no attack is useless, and the referee will eventually penalize a passive fight.
Grips that get a shido
The IJF regulates gripping in its refereeing rules, and those rules change every Olympic cycle. The stable principles are these. You get a shido for avoiding a grip, for breaking the opponent's grip with both hands, or for putting your fingers inside uke's sleeve or trouser leg. Some non-standard grips (cross grip, one-sided grip, belt grip) must be followed quickly by an attack. Grabbing the legs is penalized as well.
For the exact current list, check your federation's rules. Youth events often run the same principles with a few adaptations.
Grip fighting drills
Kumikata is trained like a technique. Four simple drills:
- Grip randori: 30 seconds where the only goal is to get your grip. No attacks. Hold your grip for three seconds to score a point.
- One hand vs two: uke may only use one hand while tori fights for a full grip.
- Forced kenka-yotsu: a right-hander plays left-handed for a whole round of randori.
- Towel or gi pull-ups for finger and forearm strength. The page on judo strength and conditioning has more.
Fingers suffer quickly with this work. If the joints swell, finger taping helps protect them, and pain that lasts calls for a doctor's opinion.
Reading your opponent's grip
An opponent's kumikata tells you a lot before they attack. Someone who takes the lapel very high is often setting up a forward throw. Someone who drags the sleeve down wants to break your posture. Watch, and write down what the opponents you meet often in competition do. The method is laid out in judo opponent scouting.
All 40 throws of the gokyo start from a grip. Our advice for this season: pick one main grip and one backup, such as sleeve-lapel and double sleeve, and build your attacks from those two only.
