Kendama ( けん玉 )

Souce: Wikipedia

Old-style traditional kendama not for competition use.

A kendama (けん玉 , also written as 剣玉 and 拳玉) is a Japanese toy that consists of a hammer-like object with a ball connected to it by a string often called in English ring and pin.

Red Ozoora kendama made by the Yamagata Koubou factory in Japan. The green mark says that it is approved by the Japanese Kendama Association for competition use.

Kendama play consists of catching and spearing the ball in various ways or performing various juggles, balances or position sequences. A book published by the Japan Kendama Association describes 100 "wazas" and an article in a JKA publication diagrams over 2,000. A Japanese maker of competition kendamas says that 30,000 exist.

Most people play with kendamas for personal satisfaction, but competitions take place, especially in Japan, in which lists of wazas must be performed in sequence, wazas must be performed repeatedly for as long as possible or wazas must be performed head to head with a rival until one fails to complete a waza.

The ball—called a tama (玉)—has a hole in it, and it rests on a spike (the ken) on the top of the kendama. The hammer-shaped handle is called the ken (剣, lit. "sword"). The two extending sides of the ken are concave cups; one is smaller than the other. The larger cup is called the ōzara (大皿, lit. "large dish") and the smaller cup is called the kozara (小皿, lit. "small dish"). There is also an even smaller cup called the chūzara (中皿, lit. "middle dish") at the bottom of the handle.
