This video is the performance of Atsuko Wakai of Japan at World Karate-do Federation (WKF) Championship 2004.
She is undefeatable kata player. No wonder: She's great!
Diferrent from my style, Shotokan, her style is Goju-ryu. She performed "SuperRinpei" kata, the most difficult kata in Goju-ryu because it is a long enough kata (about 3 minutes), some techniques are difficult, and the last one, need a perfect hara to do this kata.
Please take a look...
