Tai Otoshi is a fundamental throwing technique in judo, classified as a hand technique. It involves using the opponent's momentum against them by stepping to the side and pulling them down while simultaneously using your body weight to unbalance them. The throw is executed by gripping the opponent's collar and sleeve, creating leverage to bring them to the ground. This technique is effective for both beginners and advanced practitioners, as it emphasizes timing and balance. Tai Otoshi can be used in various situations, making it a versatile tool in a judoka's arsenal. Proper execution requires practice to master the necessary movements and body mechanics.
