Niseishi Kata & Bunkai
The kanji naming the kata translates to simply 24, with an optional component implying steps or techniques (waza in Japanese).
Like most karate kata, Unshu's origins are likely traceable back to China (Sells, Unante; ISBN 0910704961). The most common of today'sversions are derived from Aragaki (Arakaki) Seisho who lived in Okinawa from the mid-1800s, to the early 1800s .
The Shotokan "Nijushiho" version is a derivative of the Shito-ryu version, in a similar manner to the heaian kata having been passed to Funakoshi by Mabuni (however in this case Nakyama sensei played a key role in its transmission from Mabuni to Funakoshi sensei).
The kata is performed by Jason Armstrong, 7th dan
support through Renshi Jason Griffiths (5th Dan) to add Shotokan & Okinawan commentary to the Shito-ryu form/bunkai. Its heritage is covered and the video demonstrates the kata
