New Version of Kata Performed by Sensei M. Yahara JKA
This kata, as explained earlier in Kanku-Dai, derives from Kanku-Dai introduced into Okinawa by the Chinese envoy Koshokun. Kanku-Sho (the suffix - Sho, 'lesser' or 'minor', indicating its origins) was created by Master Yasutsune Itosu.
The basic embusen or configuration of the two Kata is very similar in essence, but Kanku-Sho devotes most of its attention to middle-level techniques, in contrast to the upper-level bias of Kanku-dai understanding this should make students aware of such considerations as the difference in height necessary in the two jumping techniques. Often we see height off the ground being made the main criterion in both whereas, although it is vital factor in the first (to avoid having one's feet swept by Ashi-barai or Bo), to jump high in the second would be to leap straight into your opponent's attacking technique.
The Kata enables practice in both realising oneself from wrist grabs and in seizing and pulling an attacker onto a counter. It also offers practice in defending against attackers with sticks and multiple attackers demanding the use of simultaneous blocks with both arms.
In the latter instance, however, it should be pointed out that in this and many Kata, where double blocks seem evident, it is not always the case. Here, in left back-stance the right fist swings back behind the head in Jodan Uchi-uke whilst the left hand simultaneously swings to the front in Gedan-barai.
This technique is not necessarily to block an attack to the rear as well as to the front, but, just as with Jodan Morote-uke in Jion, for example, it is to ensure that both sides of the body are balanced and brought into action together, thus strengthening the Kime and, therefore, the effectiveness of the main block.
