Ryukyukoku Matsuri Daiko (AKA: RMD) literally translates to "Ryukyu Kingdom Festival Drums". Ryukyu Kingdom is the ancient name for what is presently known as the Okinawa prefecture of Japan. Located just southwest of mainland Japan and northeast of Taiwan, it consists of about fifty islands, of which Okinawa is the largest. Due to its unique location, its culture and traditions have been greatly influenced not only by Japan, but also China, Korea and Southeast Asia.

RMD is modeled on the traditional drum dancing called "Eisa". Eisa is dance performed during the Bon festival, a three-day observance in Okinawa when ancestor spirits visit their families in the living world.

Unlike other forms of taiko, Okinawan Eisa taiko drummers all carry their own drum. There are three types of drums. Some drummers use the o-daiko (a large drum carried on a purple sash over the left shoulder). Others play hand drums, either the shime-daiko (a double sided, knotted or tied drum) or the paranku (a single sided drum).

RMD’s choreography is a dynamic blend of traditional Eisa and Karate forms with contemporary influences incorporating both traditional folk music and modern music.

The organization was founded in 1982 in Okinawa. It also has chapters in mainland Japan, Argentina, Brazil, Peru, Bolivia, Mexico, Los Angeles and Hawaii. The Texas chapter was established in Summer 2008.
