Aikido (Shinjitai: 合気道, Kyūjitai: 合氣道, aikidō, Japanese pronunciation: [aikiꜜdoː]) is a modern Japanese martial art which is split into many different styles including Iwama Ryu, Iwama Shin Shin Aiki Shuren Kai, Shodokan Aikido, Yoshinkan, Renshinkai, Aikikai, and Ki Aikido. Aikido is now practiced in around 140 countries. It was originally developed by Morihei Ueshiba, as a synthesis of his martial studies, philosophy and religious beliefs. Ueshiba's goal was to create an art which practitioners could use to defend themselves while also protecting their attackers from injury.
