That's 150 distinctly different kata. Most of the kata were developed on Okinawa. They are listed A-Z by their Okinawan name. Frequently these names are just the Japanese pronunciations of the Okinawan names. The characters that the names are written in are the same in Okinawa and Japan, but the pronunciation on the main islands is different from that of little Okinawa.
Okinawan pronunciation is considered rural and ethnic.
Origin Style - the name of the style of karate where the kata spent most of its life. Although many of the kata are thought to originate in China, either as shadowboxing turned stylistic or dancing used for shadowboxing, most of them spent centuries being developed on Okinawa. Also, since the Chinese connection is known only through legend, the Okinawans are given credit. I am always interested in adding to this list of kata and filling out more of the information. But that's exactly what the Okinawans did in most cases.
