As mentioned on the Home Page our study of karate as a complete martial art does include throws and grappling. We use the term Jujutsu to refer to this, but you should not confuse this with modern sport Jiujutsu or Judo. Our goal in the White Dragon Karate Training Method is always first and primarily practical self defense. See this video from Iain Abernethy on the difference between the two.
Those of you who are familiar with some or many traditional kata will recognize the movements demonstrated by the guys over at Karate Culture in this video.
