Jundokan is believed to be the best Goju in Okinawa.  It employs all the training of Miyagi Chojun, from the basics, kata, weight training, hand leg and body conditioning and so much more - it is amazing.  This DVD has a complete interview with Miyazato Ei'ichi Sensei, where he tells his entire Goju story.  The kata performances are impeccable, filmed professionally.  The production itself is absolutely perfect as well.  If you do Okinawan or Japnanese Goju, you need this DVD, as this is one of the best of the best, ever produced on the hard soft style created by Master Chojun Miyagi.
