Aikido (Japanese: 合気道? Hepburn: aikidō) [aikiꜜdoː] is a modern Japanese martial art developed by Morihei Ueshiba as a synthesis of his martial studies, philosophy, and religious beliefs. Aikido is often translated as “the way of unifying (with) life energy“[1] or as “the way of harmonious spirit”.[2] Ueshiba’s goal was to create an art that practitioners could use to defend themselves while also protecting their attacker from injury.[3][4]
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.[5]
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.[6]
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.
