It translates to 'internal divided conflict'. The form makes use of in-fighting techniques (i.e. tai sabaki (whole body movement)) and grappling. In Shorin-Ryu and Matsubayashi-ryū Naihanchi Shodan is the first ni kyu (brown belt kata) although it is taught to yon kyu (green belts) occasionally before evaluations for the ni kyu rank. It is also the first Shorin-ryu and Shindo jinen-ryu kata to start with a technique to the right instead of the left. There are three modern kata derived from this (Shodan, Nidan and Sandan). Some researchers believe Nidan and Sandan were created by Anko Itosu, but others believe that it was originally one kata broken into three separate parts. The fact that only Naihanchi/Tekki Shodan has a formal opening suggests the kata was split.

Whilst the kata is linear, moving side to side, the techniques can be applied against attackers at any angle. The side to side movements in a low stance build up the necessary balance and strength for fast footwork and body shifting. The kata are intricate strategies of attacking and defensive movement, done in either naihanchi (or naifanchi) dachi, a shoulder-width stance with the toes angled inwards, or the kiba dachi, for the purpose of conditioning the legs to develop explosive power. If one rotates one's torso a few degrees to one side or the other while performing Naihanchi/Tekki, the result is the Hachi-monji, or figure eight stance. Some researchers believe the form is a non-ballistic two-man grappling exercise.
