Aikido techniques consist of entering and turning movements that redirect the momentum of an opponent’s attack, and a throw or joint lock that terminates the technique.
Aikido derives mainly from the martial art of Daitō-ryū Aiki-jūjutsu, but began to diverge from it in the late 1920s, partly due to Ueshiba’s involvement with the Ōmoto-kyō religion. Ueshiba’s early students’ documents bear the term aiki-jūjutsu.
Ueshiba’s senior students have different approaches to aikido, depending partly on when they studied with him. Today aikido is found all over the world in a number of styles, with broad ranges of interpretation and emphasis. However, they all share techniques formulated by Ueshiba and most have concern for the well-being of the attacker.
