Kokiriko is a traditional Japanese percussion instrument. The instrument sounds like a long set of domino pieces crashing into each other and falling, and has a distinct clicking type of sound. The tool is made by mounting several wooden blocks on a leather strap. The skin has a handle at each end, with the help of which the wooden bricks collide with each other in alternating movements. This tool will certainly attract children and adults with its unconventional design. Long live skin-mounted dominoes!
