Shiho Nage
Keeping your opponent in extension in the axis of his imbalances is crucial. During shiho nage for instance, if this hands positioning is not respected, creating the necessary extension becomes impossible.

Hands positions: details
"grab your opponent's wrist so that his thumb is turned towards you"
. O Sensei - Kuden

The positioning of the hands matches exactly the hands positioning on the sword.
Here is an example of what is called riai in Aikido. Riai is the link that unifies body techniques and weapon techniques..

As for the position of the body, there is no difference between these three movements... although considered as different in the grading "catalogue".
Riai, the ubiquitous link between all "techniques" explains that Aikido is not a simple juxtaposition of unrelated movements, it is a synthesis organized around one unique principle..
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.
