Here are some good Karate kata videos for your reference. You can use these videos to help you practice and to remember your kata, though it's probably not a good idea to try to learn kata from these videos. Please take note that these Karate Shotokan kata are performed in the typical JKA-style, which is very popular but may slightly differ from what we practice at Wilcoxen's Family Academy of Martial Arts.
"The ultimate aim of the art of karate lies not in victory or defeat,
but in the perfection of the characters of its participants." - - Master Gichin Funakoshi
