Jodo means "the Way of the Stick". The jo is a staff, often made from white oak 128cm long and 2.5cm thick. Jo techniques include striking, thrusting, blocking, parrying, pinning, and sweeping, and they are usually practiced against a partner who uses a wooden sword (bokken/bokuto).
Muso Gonnosuke was the founder of Jodo and famously defeated the swordsman, Miyamoto Musashi, in the early 1600's. Please refer to the following by Kim Taylor for a more in depth history. https://www.ejmas.com/jnc/jncart_taylor_0900.htm
We train using traditional methods of of Kihon (basics performed with and without a partner) and Kata (preset movements, done with a partner). We practice the Zen Ken Ren Jo, Seitei Jo.
