Tenkotsuki is a traditional Japanese martial arts technique primarily used in Aikido. It involves a specific type of joint lock that targets the wrist and elbow, allowing the practitioner to control an opponent's movement effectively. This technique emphasizes fluid motion and the use of an opponent's energy against them. In Aikido, Tenkotsuki is often practiced in various forms, including both standing and seated positions. The goal is to neutralize an attack while maintaining balance and harmony. Practitioners learn to execute this technique with precision, enhancing their overall skills in self-defense and conflict resolution.
