Kizami zuki in Shotokan Karate refers to a technique where the lead hand executes a quick jab or punch. It is characterized by its speed and precision, aiming to swiftly strike the opponent's target area, often the face or chest, with the intent to disrupt their balance or initiate an attack sequence. This technique is fundamental in Shotokan Karate for its role in both offensive combinations and defensive maneuvers, emphasizing agility and timing in executing punches from a guard position.
