it MIGHT NOT be if the instructors at my dojo all decided to start conducting class exactly as they do in Iwama.
More relevant, it might not be Aikido at our dojo anymore if we began restricting hakama to yudansha!
I'm sorry, I may be missing your point. Are you saying that what they're doing in Iwama isn't Aikido? Or is it that dojo where only yudansha wear hakama is not Aikido? Both?
