Annan (or Anan or Ahnan (安南)) is a karate kata, which is a traditional method of recording a sequence of movements for attacks and defense. The origin and creator of this kata is unknown, but it can be assumed that like other kata, it was developed to record fighting techniques learned by Okinawan martial art practitioners from travelling Chinese martial artists.
The kata contains many palm heel strikes as well as evasive footwork. The open hand and ox-jaw fist techniques lend credibility to this kata having roots in Chinese Kung Fu. The techniques can be applied as short distance strikes and grappling to immobilize and control the opponent.
It is know that this kata has been passed down through an old style of Karate called Ryūei-ryū. This style of karate was passed down and incorporated into Naha-te and is now seen to be part of the Shito-ryu style of Karate. Norisato Nakaima is credited with bringing the kata to Naha after learning it during travels to China.
