Control of uchi jo's tsuki and yokomen executed on pictures 1,2,3. N.B., on picture 2, uke jo steps in with his left leg in front.
The pictures 4, 5 and 6 show how the end of uke jo's weapon slides with yokomen between uchi jo's both forearms following kessa giri's cutting line.
The pictures 7 to 15 show how the rotation executed by uke jo must find uchi jo's forward imbalance. Uke jo opens the right side of his body toward that imbalance by moving his right leg. He mustn't come back with his left leg otherwise he would bring uchi back in his balance.
N.B. : It is also possible for uke jo to change the position of his hands during the throw in order to strike with uchikomen at the very moment his opponent is landing.
Aikido is not a sport, it is a martial art which laws (takemusu) are in harmony with the laws of the universe. Studying them allows the practitioner to understand his place in the universe. Aikido was born in Iwama, O sensei achieved in that village the synthesis of tai jutsu, aiki ken and aiki jo.
The International Takemusu Aikido Federation (ITAF) brings to the practitioner the structure he needs in order to work as close as possible to the reality O sensei MU defined. The official national representations are the guarantee of a teaching faithful to the Founder's.
In modern Aikido, weapons are hardly taught, if taught at all. In O sensei's Aikido, on the contrary, aiki ken, aiki jo and tai jutsu are unified and form together a riai, a family of harmonious techniques stemming from one unique principle. Each techniques helps understand all the others.
Peace is a balance between a human being and the world around him. The true martial art's goal is not to become stronger than one's opponent but to find in that opponent a way to realize harmony. There is no enemy anymore as such, but an opportunity offered to reach unified ki.
