Well my first kata was Aoynagi, I learned it as a white belt! However I wasn't expected to memorize it or perfect it of course. Aoynagi is really cool especially the the one legged attack to the throat part( I think thats what its trying to portray) Oh and isn't H-Form 1 from taekwondo exactly the same as Kihon-Kata Ichi? I remember from my taekwondo days it was downblock, punch, repeat 3 punches, downblock punch then the whole thing over.( exactly what kihon kata ichi is)
