Monadnock
2nd Black Belt
I thought I'd get something started to list various styles of Jo. The jo is a shorter staff than the bo, typically around 4 feet in length, depending on style. If your style utilizes the jo, or similar, please feel free to include it here.
Shinto Muso-ryu (also called Shindo Muso-ryu)
This style was founded by Muso Gonnusuke Katsuyoshi around 1605. The 64 kata deal primarily with an opponent wielding a long sword.
Aiki Jo
This style of Jo is taught as a suppliment to Aikido training to practice Aiki principles using weapons. It was taught by Ueshiba Morihei but does not contain any koryu kata. There are solo kata practiced, often referred to as "31 kata" referencing the 31 moves.
Bujinkan
There is jo work in the Bujinkan, along with rokushakubo and hanbo, mainly attributed to the Kukishin-ryu, but other included ryu may also have jo kata.
I have heard that there may be other koryu systems that utilize the jo as well. Hopefully more users will post about their utilization of this weapon.
