Although the certain origin of nunchaku is disputed, it is thought to come from China through the Japanese island of Okinawa. The Japanese word nunchaku itself comes from the Hokkien (Min Nan) word nng-chiat-kun(no-chiat kun). When viewed etymologically from its Okinawan roots, nun comes from the word for twin, and chaku from shaku, a unit of measurement. The popular belief is that the nunchaku was originally a short flail used to thresh rice or soybeans (that is, separate the grain from the husk).
It is also possible that the weapon was developed in response to the moratorium on edged weaponry under the Satsuma daimyo after invading Okinawa in the 17th century, and that the weapon was most likely conceived and used exclusively for that end, as the configuration of actual flails and bits are unwieldy for use as a weapon. Also, peasant farmers were forbidden conventional weaponry such as arrows or blades so they improvised using only what they had available, farm tools such as the sickle. The modern weapon would be an ineffective flail.
The nunchaku as a weapon has surged in popularity since martial artist Bruce Lee used it in his movies in the 1970s, and is also featured in multiple Japanese anime and manga series.
