The **sanba (samba)** is a traditional Okinawan percussion instrument. It consists of three small bamboo or wooden plates held between the fingers and struck together, producing a lively "kachikachi" and "shakashaka" sound. This sound creates the essential rhythm for Okinawan folk songs, Eisa, Kachāshī dances, and other performances, instantly enlivening the atmosphere. Its simple yet powerful sound is characteristic, and it is an instrument that symbolizes Okinawa's cheerful and bright musical culture.
