Daito-ryu Aikijujutsu—known as the parent art of Aikido—is a Japanese martial art designed as a system of armed and unarmed defense that is effective regardless of age, strength, or weight. It enables the learning of control and neutralization techniques, joint locks, throws, off-balancing maneuvers, strikes, and pressure-point attacks, fostering both the harmonious development and the technical proficiency essential for understanding the dynamics of *Aiki*.
