Not sure: "shomen uchi ikkajo osae ichi" is a technique. Would you say "ikkajo" is a technique?
Isn't it just a matter of convention?
I'm an aikikai student.
Watching I http://www.youtube.com/watch?v=UM7XJ98gV74
I would say that shomen uchi ikkajo osae ichi
in yoshinkan is shomen uchi ikkyo omote
in aikikai and shomen uchi ikkajo osae ni
in yoshinkan is shomen uchi ikkyo ura
To me it seems that shomen uchi
(forehead strike) is the attack and the defense (elbow lock) is called ikkajo osae
in yoshinkan and ikkyo
in aikikai. Omote
are positioning variations meaning "the front" and "the back" (of the attacker).
In my experience, technique
in aikikai usually refers to what the defender does (ikkyo omote
, or just ikkyo
). One of my teachers regularly states that aikido has only a small numbers of techniques. But in some contexts, technique
refers to the combination of attack and defense (like shomen uchi ikkyo omote
), on a list of test requirements for example.
So perhaps what is commonly called a technique
in aikikai, might be called a series
in yoshinkan. I've never heard about series
