Shime Waza (Choking Techniques) - Okada Sensei now takes choking or Shime Waza to an all new level. Believe me this is one old man you do not want to get on the ground with as he can choke you a thousand different ways and still a few left over. He shows you collar choke, single wing choke, sleeve wheel choke, thrust choke, triangle choke and it just keeps on going.
