Aikido is a self-defense art from Japan that was developed by Morihei Ueshiba (1883-1969) which was introduced in the 1920’s. Its style and movements were adapted from various ancient Japanese martial arts such as Daito-ryu, Aikijujitsu, Yagyu-ryu, Kenjutsu, and others. The name Aikido is consisted of three words, Do (way/method), Ai (balance/harmony), dan Ki (life energy/spirit). Therefore, Aikido means “The way to harmonize your life energy”. In Aikido, an opponent’s attack is perceived as water that is not to be stopped nor held, but to be flowed to a safer direction instead.
