Isshinryu Kata

Seisan Kata can be found in all of the foundational styles of Isshinryu. These styles 

 include Gojo Ryu, and Shorin Ryu.

The training emphases include Seisan stance, cat stance, straight punch, side, down, and head blocks, and front snap kicks.

Seiuchin Kata training emphases introduce Seiuchin stance, open-hand blocks and strikes, shuto strikes, breaks, angles-and-directional changes, and double-elbow strikes. Seiuchin kata has strong Goju Ryu roots. In particular, in teaches the tension/relaxation technique, as manifested in focused breathing. The tension/relaxation combination of this breathing technique enhances power, while also conserving energy.

Naihanchi Kata emphasizes fighting in small spaces. Close-contact combat, where the subject defends from opponents on two sides. 

A critical element is in this kata is Gamiku, or rotation in the hips. This technique generates an enormous amount of power behind each punch and block. Naihanchi is considered to be the "Mother" kata of Isshinryu.

Wansu Kata incorporates moves from the first three katas. it also introduces techniques such as throwing, leg blocks, side-stepping, and distraction techniques, or "fakes". Wansu introduces a turn to the 45-degree angle. 

Chinto Kata is traditionally thought to be "fighting on a bridge". Essentially, the subject is in a narrow space, such as a bridge or corridor, and must defend opponents approaching from either side.   This kata emphasizes turns on a 180 angle. Jump kicks are introduced. Hard and soft deflections as well as attacks are integral techniques in this kata.

Kusanku Kata is thought to be "fighting in the dark", or "fighting by touch". It presents multiple attackers. The  kareteka is taught to crouch very low to the ground in this kata, as if to avoid being detected in the dark of night.

Sunsu Kata is the only Isshinryu kata developed exclusively by Master Shimibuku. It is considered to be the "Offspring" kata of Isshinryu. This kata incorporates all of the stances, empty and closed hands techniques, and kicks from all of the previous katas. Speed, power, and a wide range of combat techniques are demonstrated in this kata.

Sanchin Kata focuses on breathing, tension, and control. In a well-executed Sanchin kata, every muscle group in the body is engaged simultaneously. It develops inner control, focus, and breathing stamina. Sanchin kata is considered to be the "Father" kata in Isshinryu.
