The kendama (けん玉, "sword [and] ball") is a traditional Japanese skill toy. The ken has three cups and a spike which fits into the hole in the ball. The kendama is a variant of the classic cup-and-ball game, and the Hispanic world toy known as boliche or balero. The principle of these toys are the same: catching one object with another, where both are joined by a string. However the modern kendama style takes influences from a diverse range of skills including yo-yo, diabolo, and juggling.
