Sumo features a wide variety of techniques, and among them, “Hazu-oshi” is a fundamental yet practical pushing technique. Especially for beginners or foreign fans of sumo, understanding techniques like Hazu-oshi is a perfect way to get into the sport. In this article, we’ll explain the basics, movements, characteristics, practice tips, and tactical uses of Hazu-oshi in a way that’s easy to follow.


What is Hazu-oshi? Understanding its Role Among Pushing Techniques

Hazu-oshi is a pushing technique where a wrestler applies force from the outside of the opponent’s upper arms, targeting the area near the back of the shoulders. This move excels at breaking the opponent’s balance while maintaining distance and control. Unlike a head-on push, Hazu-oshi lifts the opponent’s arms upward and outward, disrupting their posture.

Sashite-wazaUnderarms, torsoVery closeGet inside for throws or holds

Hazu-oshi is known for its balance of offense and defense, making it ideal for learning proper form and control.


Basic Movements and Body Mechanics of Hazu-oshi

The key to Hazu-oshi lies in pushing upward while moving forward, without losing your own balance. Here’s how the motion works, step by step:

  1. Take a proper stance: Stand with feet slightly wider than shoulder-width and lower your center of gravity.
  2. Position your hands: Place your palms on the outer sides of the opponent’s upper arms.
  3. Push upward forcefully: Use your lower body strength to lift and press upward.
  4. Step forward while pushing: Move in as you push, disturbing the opponent’s balance.
  5. Follow up with a finish: Once the opponent is off-balance, continue with a push-out or transition to another technique.

The angle of the push and the stability of your posture are critical. If the upward force is weak, your opponent may easily resist or counter the movement.


Key Points and Practice Tips for Beginners

For beginners practicing Hazu-oshi, there are important points to keep in mind to avoid ineffective form or injury.

Key PointExplanation
