The history of Pangainoon and Uechi ryu karate seems to begin with Shushiwa. Shushiwa is the Japanese pronunciation of Chou Tsu Ho. Chou Tsu Ho (or Chu Chi Wo) was born in 1874 in Nanko-chin Shibata village in the Zhitian area of China.

As least two different backgrounds have been established for Shushiwa. The same is true for the art of Pangainoon which he taught to Kanbun Uechi in the latter part of the 19th century.
