Its history and essence is explained here in brief!
Kabuki came into existence around 1603 with the arrival of a troupe of dancing girls in Kyoto led by a certain Izumo-no-Okuni, formerly a shrine maiden. Their dances created a sensation and were labelled "Kabuki" which, at that time, meant "unorthodox" or "eccentric."

Such troupes of women were subsequently banned as were those of the dancing boys that took their place.
They were succeeded by groups of adult men whose performances developed into Kabuki as it now exists.
In the process, the original meaning of the word kabuki changed to become Ka(Song), Bu(Dance), Ki(Technique or Skill).
Kabuki originally consisted of short dances but the repertoire now is huge and is made up both of plays and dances, most of which date from the seventeenth and eighteenth centuries.

Originally the principal entertainment of the urban merchant classes, Kabuki is the traditional, popular theater of Japan and continues to flourish and draw large audiences.
Kabuki is also attracting increasing attention abroad and is now regarded as one of the world's greatest theatrical arts, remarkable for its vigour.
