The World Oshukai Okinawa Shorin-Ryu Karate Do Kobudo Federation (short name W.O.F.) is a non-profit organization dedicated to the practice and spreading of true traditional Okinawa Shorin-Ryu Karate and Okinawa Kobudo. The W.O.F. was created by okinawan master Kenyu Chinen. Before W.O.F. master Chinen was a international representative of two okinawan organizations: Okinawa Shorin-Ryu Karatedo Association leaded by master Katsuya Miyahira, and All Okinawa Kobudo Federation, leaded by master Shinpou Matayoshi. Joining two basic schools from Okinawa Karate and Kobudo to the one organization turn to be a very good decision. Today W.O.F. has its representatives in many countries on five continents. The Headquarters of World Oshukai Okinawa Shorin-Ryu Karate Do Kobudo Federation is in Tomigusuku, Okinawa – Japan.
