Gekisai Dai Ichi
Gekisai means "attack and smash". They were created by Chojun Miyagi in 1940 and are beginner's kata,the first to be learned in some styles.
It begins with a 90 degree turn to the left in left Sanchin Dachi with a left-hand Jodan Age Uke, followed by stepping into right Han Zenkutsu Dachi and executing Jodan Oi Tsuki. Next is a step backwards with the right foot 90 degrees to Shiko Dachi with a Gedan Harai Uke over the left knee. The entire sequence is then repeated to the right in opposite stances (ie: right instead of left, etc.) ending up facing back in the starting direction.
Stepping into left Sanchin Dachi, perform left Chudan Yoko Uke. Step forward and repeat with right stance and block..Next is a left Chudan Mae Geri stepping into left Zenkutsu Dachi, followed by 3 techniques with the left hand, namely Hiji Ate, Jodan Uraken Uchi and Gedan Barai, followed by Chudan Gyaku Tsuki.
Next, turn 90 degrees to the right and execute a right Ashi Barai landing in Hachiji Dachi, then deliver a right Jodan Yoko Shuto Uchi. You then step forward into left Sanchin Dachi, perform a left Chudan Yoko Uke (In the Ni version, a Kake Uke is substituted for the Chudan Yoko Uke. This is followed by stepping forward in Sanchin Dachi and then back, swiftly, executing the Kake Uke techniques), and then repeat the Chudan Mae Geri into Zenkutsu Dachi-Hiji Ate-Jodan Uraken Uchi-Gedan Barai-Chudan Gyaku Tsuki combination using the right side instead of the left, followed with a repeat of the Ashi Barai-Hachiji Dachi-Jodan Yoko Shuto Uke moves.
Up until this point, Ichi and Ni are identical (with the exception of a more pronounced foot stomp going into the Hachiji Dachi stances and the Kake Uke substitution mentioned earlier). The ending technique is different. In Ichi, you step back into right Zenkutsu Dachi and deliver a left Seiken Awase Tsuki, then slide the left foot up into Heiko Dachi. You then slide the right foot back into left Zenkutsu Dachi while simultaneously performing Migi Chudan Uchi Uke and Hidari Chudan Yoko Uke, and then delivering a right Seiken Awase Tsuki. Yame.
In Ni, from Hachiji Dachi, slide the left foot back on a 45 degree angle into right Neko Ashi dachi while performing Tora Guchi, then use Suri Ashi to slide the right foot to the opposite side at 45 degrees from center and repeat with Tora Guchi. Yame.
