Ikkyo

 

The video below shows the technique Ikkyo (jap. "first teaching") aka Ikkajo ("first principle") aka Ude-osae ("forearm pin") in some usual forms.

 

The focus here is in tori's hand movements: forearm rotation and changing wrist position. 

Practice roles

 

Aikido is practiced with these roles:

 

Tori = the one who is performing the technique (aka "Nage" or "Shite").

 

Uke = the one who is receiving the technique (aka "Aite").

Directions

 

Omote = front of uke.

Ura = behind uke.

 

Irimi = to enter (move ki forward).

Tenkan = to turn (change direction of ki).
