Gyakuzuki

Gyakuzuki, also romanized as gyaku-zuki, is a fundamental straight punching technique in many Japanese martial arts, particularly karate. The term means “reverse punch” or “opposite punch,” and it is executed with the arm opposite the lead leg.

In execution, the punch is delivered from the rear hand, typically from a chambered position near the hip. The practitioner drives the punch forward along a straight line toward the opponent, often while rotating the hips and shoulders to add power. The weight transfer and torso rotation help generate momentum, and the fist typically finishes with the wrist aligned to transfer impact efficiently. The technique is commonly practiced from stable stances such as zenkutsu-dachi (front stance) but can be adapted to other stances in kihon, kata, and kumite.

Gyakuzuki is contrasted with oi-zuki, the lunge punch delivered with the lead hand. Variations exist among styles: some schools use a vertical fist at impact, others a horizontal fist; the exact body alignment and timing can differ, but the core concept remains the same—powerful, straight-from-the-hip punch delivered with the rear arm.

In training, gyakuzuki appears in kihon drills, forms (kata), and sparring routines, valued for developing hip rotation, core engagement, and the ability to respond with a direct, rapid strike from a defensive or neutral position.
