Development of aiki-jō

Much of the aiki-jō syllabus was developed by Morihei Ueshiba (植芝盛平 ''Ueshiba Morihei'', 1883–1969) at his dojo in Iwama, Japan, at the same time he developed aikido's sword training (called '' aiki-ken''). It is well documented that Ueshiba studied several different styles of martial arts, including the art of the spear (''

'') and the modern art of the bayonet or " Jūkendō". The aiki-jō techniques taught by Ueshiba were a distillation and modification of that training, with an emphasis upon the use of the ''jō'' as a method for the refinement of one's empty-handed aikido techniques. Some practitioners of traditional Japanese martial arts have noted that aiki-jō techniques bear more resemblance to jukendo (bayonet fighting, which Ueshiba studied during the

Aiki-jō Practice

Aiki-jō practice can help uncover errors in the student's empty-handed aikido technique, and provides an opportunity to apply the principles of aikido in different situations. Saito codified three sets of techniques, the first being twenty ''suburi'' (solo cutting exercises), the second being ten partnered forms, and the third being two ''

'' (solo forms). Some dojo also practice ''jiyu-waza'' armed with ''jō'' (a freestyle technique without a predetermined form of attack and response).

Suburi

, a word that translates literally to something like "elementary swinging", is used to refer to the basic solo movements of aiki-jō, developed by Saito as a distillation of the forms and partnered practice. There are twenty aiki-jō ''suburi''. They are divided into sub-groups and named as follows (the English given is an approximate translation): :Five Movements 1.

Kumijō

The partnered forms practice of aiki-jō is called , meaning the crossing/meeting of staves. There are ten ''kumijō'' in Saito's aiki-jō curriculum. Ueshiba originally taught various partnered drills and techniques with the ''jō'', and Saito originally codified them into a discrete series of seven such partner drills. In 1983, Saito was set to give a public demonstration, and so devised three more ''kumijō'' at that time. The ''kumijō'' teach students how to alternately control the center line and move off of it to avoid attacks as well as how to blend with an opponent's attacks, among other skills. Improvisational variations on the ''kumijō'' (called ''henka''), which generally cause the ''kumijō'' form to end early with one person taking advantage of an opening to strike or throw the other, are also taught.

The first is called "''Sanjūichi no Jō''", generally referred to in English as the "Thirty-one Point ''Jō Kata''", and was taught by Ueshiba. The second one is "''Jūsan no Jō''"; "Thirteen Point ''Jō Kata''". The third one is "''Roku no jō''". There are also well known partnered versions of these forms, called ''bunkai''.
