31 Jo Kata by Saito Sensei
I've found a really amazing video of Takemusu Aikido Founder Morihiro Saito Sensei showing the 31 Jo movements. The clip is located at Youtube, has a great visual quality and an annoying french dolmetcher.
As you may recognize by visiting the video-link, there are also other aikido related clips. Even some black & white videos of O'Sensei Morihei Ueshiba doing technique. Enjoy!
