The clenched fist is the likeness of the fist of Miyagi Chojun, Sensei,
the founder of GoJu Ryu. 
It was first used by Yamaguchi Gogen, Sensei,as the symbol of his KaraTe club at Ritzumeikan University in Japan. It later became the symbol of the Nippon GoJu Kai, and was adopted by his student Peter Urban, Sensei, as the symbol of USA GoJu. Urban changed the kanji writing on the wrist and ribbon of the original, to the English writing of USA GoJu. We have eliminated all of the writing on the wrist and ribbon, and changed the color to red.
