What is "kendama"

is a traditional Japanese toy. The ken has two cups and a spike which fits into the hole in the ball.

Kendama bears similarities to 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, juggling and dance.
