Some basic comments on the form and structure of Koshiki no Kata...
- Koshiki no kata is composed of two groups of techniques. The first set is named Omote, suggesting that it is preliminary or superficial knowledge. The second set is named Ura, suggesting that it exemplifies more profound understanding of the principles of the kata. So, basically the kata progresses from superficial toward profound.
- Omote is composed of seven pairs of techniques. Each pair explores similar or same attack conditions but uke either resists or modifies the attack to determine which of each pair comes to pass.
- Ura is composed of seven techniques that are done rapidly and continuously.
