Aiki Segi

Aiki Segi is a concept originating from the martial art of Aikido, specifically within the Iwama Ryu lineage. It refers to the dynamic connection and harmonious blending of movements between uke (the receiver of the technique) and nage (the person executing the technique).

While "aiki" generally translates to "harmony" or "joining energy," and is a core principle of Aikido, "segi" is less universally defined. Within Iwama Ryu Aikido, founded by Morihiro Saito Sensei, "segi" emphasizes the importance of precise body positioning, timing, and distance relative to the opponent. It's often described as the "structure" or "framework" within which aiki can manifest.

Therefore, Aiki Segi can be understood as the structural and positional alignment that allows for effective and efficient application of Aiki principles. It emphasizes not just blending with the opponent's energy, but also establishing a favorable physical position relative to them to control their balance and movement. Aiki Segi is not a specific technique, but rather a principle guiding the execution of all techniques. It underlines the necessity of maintaining correct posture, distance, and timing to maximize the effectiveness of Aikido. It highlights that without proper structure (segi), aiki becomes difficult to achieve and maintain.

In practice, understanding and applying Aiki Segi involves carefully observing and responding to the opponent's movements, adjusting one's position to break their structure, and maintaining control of the center line.
