The versatility of the jo comes from it symmetry. Unlike the bokken both ends are used as well as both hands and single hand movements. Like the bokken, the jo is a training tool to extend and improve your Aikido. Jo practice is divided into: Suburi, Jo Kata, Kumi Jo, Jo Tori and Jo Kokyu Nage.

These are sequences of individual jo movements which are used to improve jo techniques and introduce movement. There are two kata: one with 13 steps (juu-san no jo) and one with 31(san juu ichi no jo).
These are practiced with a partner. There are 6 forms and each form contains variations.
These techniques are used to disarm an uke that is attacking with a jo.
