After the Wakashu Kabuki performed by young boys wearing a youthful hairdo before the coming-of-age ceremony had been prohibited, they shove off the forelock hair to perform Kabuki. Since the head without the forelock hair is called Yaro Atama, the Kabuki performance given by those who had Yaro Atama was called Yaro Kabuki.
Until then, Kabuki was mainly a song and dance performance. However, Yaro Kabuki was developed into a theatrical production that has a complex story with scenes changing as the time passes by.
