Strike the ken so that you take uchi's cut : check that the line of the ken is outside your body but that the line of your jo pierces uchi's body.
At that stage, uchi mustn't put any pressure on the left on the jo. In reality, the jodan gaeshi aims at the head, any lateral pressure is irrelevant.
Jo : strike migi hanmi tsuki.
Ken : step on the left and grab the jo from below with your left hand. Jo : immediately step on the right, drawing a spiral up with the jo so that you unbalance uchi on the rear and lock his wrist in nikyo.
While rotating, apply a second spiral in the same direction which unbalances uchi forward. Keep rotating and apply a third spiral which hooks his arm (in reality a strike on the neck ) and brings uchi in his left side imbalance.
This movement requires a perfect realization of tenkan. At the end you will have achieved a 270° rotation.
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.
