Kusarigama is a traditional Japanese weapon that consists of a Kama - a type of Japanese sickle attached to a metal chain (Manriki) with a weight at the end. It is one of the weapons used by the Ninja.

The length of the chain is from about 2.5 to 3 meters. The chain can be attached both to the handle and to the side of the sickle. The handle of the sickle at Kusarigama is usually longer than that of the ordinary Kama. 

Most techniques for using Kusarigama are found in Budo and Ninjutsu schools. The weapon is held with both hands, with one gripping the sickle and the other the chain. It (the chain) is thrown at the enemy in order to stun or entangle him with his weapon, after which he immediately attacks with a sickle. The greatest subtlety is the Maki technique (accurate throwing of the chain). The art of using Kusarigama is called Kusarigama-Jutsu.
