Aikido.

Aikido is a martial art that was developed at the beginning of the 20th century by the Japanese Morihei Ueshiba. It is characterised by fast and precise techniques, as well as circular and flowing movements that are used for effective defence.

The term Aikikai most commonly refers to the Aikikai Foundation (公益財団法人合気会, Kōeki Zaidan Hōjin Aikikai), which is the original and parent organization for the martial art of Aikido.
