Naihanchiナイハンチ

Naihanchi (ナイハンチ) is a foundational Shorin-ryu kata performed entirely in a straddle stance (naihanchi-dachi), moving laterally along a single line. The name is often rendered as "internal divided conflict" or "fighting sideways." It develops rooted stance, hip power and close-quarter techniques including grappling and in-fighting.

It is one of the core kata Kyan transmitted; in Shorin-ryu and Matsubayashi-ryu, Naihanchi Shodan is typically the first brown-belt kata. There are three Naihanchi (Shodan, Nidan, Sandan); the first is by far the most widely taught. Known in Shotokan as Tekki (鉄騎) — in the Kyan/Seidokan line the stance and stepping differ from the Shotokan/Tekki rendering.
