What is Okinawan Kobudō?
Okinawan Kobudō ('old martial way') is the traditional weapons martial art of Okinawa (formerly Ryukyu Kingdom), formalised in the late 19th century though rooted in centuries-old peasant + Pechin-warrior weapons practice. Practices bo (6-foot staff), sai (twin truncheons), tonfa (side-handle batons), nunchaku (linked sticks), kama (sickle), eku (oar), tekko (knuckle), tinbe-rochin (shield + short spear), kuwa (hoe). Traditionally taught alongside karate as complementary art. Competition scored on kata (solo form 1-3 min), team kata (3-person synchronised 2-4 min), and bunkai demonstration (application 60-90 sec). Preserved by Taira Shinken's Ryukyu Kobudo Hozon Shinko-kai (est. 1955, Naha) and World Kobudo Federation. Not currently Olympic — karate debuted at Tokyo 2020 with kata but not Kobudo.
