Gekisai Sho - 撃塞小, is the second of the Gekisai Kata, and translated into: ‘Attack and Destroy – minor’. Dai means ‘big’ and Sho means ‘small’, is this just another method of labelling Kata as an alternative to using numbers? Both Kata teach strength through fluidity of motion, mobility and the utilization of various techniques. Flexibility of attack and response will always be superior to rigid and inflexible strength.
Gekisai Dai and Gekisai Sho were developed from Sosai Masutatsu Oyama’s training under Nei-Chu So sensei short after the WO II. Master So was a top student of Chojun Miyagi sensei, founder of the Gōjū-ryū 剛柔流, one of the main traditional Okinawan styles of Karate, featuring a combination of hard and soft techniques. Chojun Miyagi developed Gōjū-ryū from the Naha-Te - 那覇手 system of Okinawan Karate, which originated from Southern Chinese Kempo.
Gekisai Kata were orginated in Okinawa by Soshin Nagamine and Chojun Miyagi sensei from Fukyu Kata Ichi and Fukyu Kata Ni. Chojun Miyagi adopted Fukyu Kata Ni as Gekisai Dai Ichi and went on to develop Gekisai Dai Ni with its Naha-Te influence as a training Kata into the Gōjū-ryū curriculum in 1940 for school children and adolescents.
These Kata were intended to make Karate more accessible for people to learn and the purpose was to teach strong and powerful movement combined with fluidity of motion and the utilization ofvarious techniques. Both Gekisai Kata belong to the so-called Kaisho Kata. These types of Kata are what you might call relaxed, because after each technique (given with maximum tension) there is relaxation. This relaxation allows a swift execution of the next technique. This is in line with the meaning of Gōjū-ryū, which translates as hard-soft.
Gekisai Sho is known as a Southern Kata within Kyokushin Karate, developed from Mas Oyama's training under Nei-Chu So sensei and not directly imported from Goju Ryu. Sensei So was a student of Gogen Yamaguchi (Goju-ryu) in Japan. Chojun Miyagi developed Goju-ryu from the system of Okinawan Karate, which originated from Southern Chinese Kempo. Southern Kata generally involve shorter movements and a closer fighting distance between opponents, Maai - 間合い, based on the slippery, wet terrain of southern China. Techniques are generally tighter and more circular than those of the Northern Kata.
