Koryu (古流 ) translates as old (古) stream (流). Different streams of water ultimately flow from a single source, like a spring. The analogy is that all martial arts systems ultimately represent one single essence. Kan (館) means hall or more loosely translated, school. Hence Koryukan refers to a school where old-style martial arts are practiced.

Koryu Uchinadi (古流沖縄手 means old-style Okinawa (沖縄) hand (手). The Di (hand) is the same charater as the Te (手) in Karate (空手). It comes from the term Toudi (唐手), which is the original name for Karate on Okinawa. Toudi means Tang hand, which refers to the combative traditions dating back to China’s Tang dynasty. Koryu Uchinadi could therefore be interpreted to refer to old style martial arts practices dating back to ancient China as practiced on Okinawa.
