The Kendama

The kendama (けん玉, "sword [and] ball") 

This stylish Kendama is an extremely addictive wooden skill toy that comes from Japan. It strengthens hand eye coordination, balance, and reflex. It can be played by young and old alike. There are endless trick possibilities for both the beginner and the seasoned master.

The Kendama is made up of the “Ken” (handle) has three cups and a spike which fits into the hole in the ball and the “Tama” (ball), which is connected by a string. The Kendama tricks are done by variations of juggling the ball in the 3 cups, spiking the ball with the Ken spike, and balancing both in new creative ways.

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, juggling and dance.
