Martial intent
Absorb a lateral throw without landing on the hip or hitting the head, by distributing the energy along the side of the torso and through the arm strike.
In short
This is an essential lateral falling technique (Ukemi) used to stay safe during throws.
The idea is to transform a sideways fall into a controlled movement: you form a curved shape with your body and strike the mat with your arm to absorb the impact.
This technique works by distributing force over a large surface area, which protects the head and joints.
It is a fundamental safety skill that every judoka must master before practising throwing techniques.

⚠️ 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
- From a standing position, slightly bend the legs and orient the body to the right or left side.
- Tuck the chin toward the chest to protect the head and neck.
- Let the body descend laterally, forming a gentle curve with the torso, without falling onto the hip.
- Strike the tatami with the arm on the falling side, arm relaxed, palm open, close to the leg and in the natural line of the body.
- Receive the contact on the side of the torso, never directly on the hip or the spine.
- Keep the legs together and slightly bent, feet close to the mat.
Key points
- Chin tucked, without excessive tension, to protect the head and neck.
- Body slightly rounded and engaged, with contact on the side of the back, never on the hip or spine.
- Striking arm long but relaxed, palm open, striking close to the leg, in the natural line of the body, without locking the elbow.
- Strike synchronised with the reception, to accompany the impact rather than anticipate it.
- Legs together and slightly bent to stabilise the pelvis.
Recommendations
To improve the effectiveness of your Yoko-ukemi, focus on smooth coordination between the descent of the body and the arm strike.
The strike should accompany the reception, with an open hand and a relaxed arm, directed diagonally relative to the torso.
The goal is not to create impact, but to progressively distribute the energy of the fall across the entire contact surface, from the torso to the arm.
Common mistakes
Beginners often land directly on the hip, instead of distributing the impact along the side of the torso and cushioning the fall with the hand strike.
This error is usually caused by apprehension, which prevents the body from rounding correctly.
How to fix them
- Accompany the lateral fall by controlling the descent of the body toward the side, so that initial contact occurs on the flank / side of the torso.
- Control the lateral descent by slightly bending the legs and directing the movement sideways rather than straight downward.
- Cushion the impact with the open free hand, guiding it toward the tatami at the moment the flank makes contact.
