Okinawan Kobudō (古武道; also known as Ryūkyū Kobujutsu, Koryū, or just as Kobudō) is a Japanese term that can be translated as “old martial way of Okinawa“. It generally refers to the classical weapon traditions of Okinawan martial arts, most notably the rokushakubo (six foot staff, known as the “bō”), sai (short unsharpened dagger), tonfa (handled club), kama (sickle), and nunchaku (nunchucks), but also the tekko (knuckledusters), tinbe-rochin (shield and spear), and surujin (weighted chain). Less common Okinawan weapons include the tambo (short staff) and the eku (boat oar of traditional Okinawan design).
