The original aiki of Morihei Ueshiba included no sutemi waza. All that is the development of Minoru Mochizuki, founder of yoseikan.
The sutemi waza, you are correct, were a vital part of old-style aikido.
Best to you.
David, I'm assuming you meant "The atemi waza, you are correct, were a vital part of old-style aikido." Correct?
Modern (meaning the French stuff) Yoseikan, isn't my bag. Older, Mochizuki Sensei Senior Yoseikan, is pretty cool stuff. Chop sockey chambarra with takedowns is probably a lot of fun however.
