Kendama

The kendama (けん玉, "sword [and] ball") is a traditional Japanese skill toy. It consists of a handle (ken), a pair of cups (sarado), and a ball (tama) that are all connected together by a string. On one end of the ken is a cup, while the other end of ken is narrowed down, forming a spike (kensaki) that fits into the hole (ana) of the tama. The kendama is the Japanese version of the classic cup-and-ball game,[1] and is also a variant of the French cup-and-ball game bilboquet. Kendama can be held in different grips, and the tricks and combinations that can be done are limitless. The principle of these toys is the same: catching one object with another, where both are joined by a string.
