This video introduces the kata "Aragaki Seisan" from which the shotokan Kata 'Hangetsu' is derived. It also teaches the fundamental fighting skills which the kata exemplifies: control, unbalancing, leading and countering using the secret Kyusho-Jutsu and Tuite methods against the anatomically vulnerable points of the attacker's body, and gives graphic examples of the effectiveness of the techniques hidden within the kata. A superb video of benefit to all interested in understanding the common principles of combat upon which the kata rest!
This older video recording is not of the same standard as current editions, but has interesting and valid content.
