Kata is the corner stone of Shotokan Karate. Katas contain all the techniques available to use in self defence situations and should be studied vigerously until they are understood. Sensei Steiner is the writer and editor of the largest source of Shotokan Karate Kata available. The website www.shotokankata.com has been online for over 9 years and details every move and technique in every kata. If you are learning a kata, this is the best place to help you get the most of your training.
