Martial intent
The judoka (Tori) performs a large outside reaping motion on the partner’s leg (Uke) to throw him backward.
In short
This is a fundamental throwing technique (Nage-waza) in judo, and is often one of the first techniques taught to beginners.
The principle is simple: using your leg like a broom, you reap the back of your partner’s leg to project him backward.
It is not a matter of brute strength, but of correct positioning and precise timing.
This technique works by combining three elements: you drive the upper body backward, you remove the opponent’s base of support, and you use the weight of your reaping leg.

⚠️ This technique should be learned and practised in a club under the supervision of a qualified instructor. The explanations below do not replace supervised judo training.
Steps
1. Kuzushi (imbalance): Push your partner (Uke) backward and slightly to his right side, with one hand on the back of the jacket and the other controlling the sleeve.
2. Tsukuri (entry): Step forward with your left foot, placing it close to Uke’s right foot, while bringing your upper body close to his hip.
3. Tsukuri (final positioning): Extend your right leg behind Uke’s right leg, maintaining continuous backward pressure with your upper body.
4. Kake (throw): Reap Uke’s entire leg toward you with your right leg while driving his torso backward.
5. Finalisation: Accompany Uke to the ground, maintaining arm control until contact with the mat.
Key points
- Rear imbalance (Kuzushi) must be established before the reaping action to ensure effectiveness.
- Keep your centre of gravity low and stable throughout the execution.
- The reaping action relies on the weight of your leg, not on muscular strength.
- Your chest and hips must remain in close contact with Uke to transmit kinetic energy effectively.
Recommendations
Focus on timing, especially the precise moment when Uke transfers his weight onto the leg you are about to reap.
At that instant, Uke’s leg functions like a rigid pillar: your reaping action can topple it like a tree, rather than pushing against a flexible limb that would simply absorb the force.
Common mistakes
Beginners often rely on muscular strength to perform the reaping action instead of exploiting gravity and the natural weight of the leg.
They attempt to attack the leg directly, trying to hook the foot without first establishing imbalance.
This poor positioning creates a clear opportunity for Uke to counter the technique.
How to fix them
- Focus on the placement of your supporting foot.
- Maintain close contact with your upper body and hips.
- Swing your reaping leg toward Uke’s thigh in a controlled, pendulum-like motion.
