Shirabyōshi (白拍子) were female dancers, prominent in the Japanese Imperial Court, who performed traditional Japanese dances (the dances themselves were also called shirabyōshi). They danced dressed as men. The profession of shirabyōshi developed in the 12th century. They would perform for the nobility, and at celebrations.
They are sometimes referred to as courtesans in the English language, but that term refers to a high-class prostitute, so this is rather incorrect. By nature they were performers. Some shirabyōshi did sleep with their patrons and give birth to nobles' children, but this was not their intended purpose as entertainers.
Shirabyōshi came about in the late Heian period. It was a time of cultural change, so in order for some women to survive they turned to performing. After their inception, Japan experienced a shirabyōshi boom in which many women became shirabyōshi because of their popularity. A shirabyōshi was always a woman who dressed in men's attire, performing dances for the gods. The name shirabyōshi meant "white rhythm", partly because of their make-up, and because their songs were slow and rhythmic. They were required to be educated, including being able to both read and write—they were talented poets, musicians, singers, and dancers.
It has been said that the shirabyōshi culture greatly influenced Noh drama by bringing forth kusemai, an unorthodox form of dancing, and introducing it to Noh.
Shirabyōshi were recognizable for the outfit they would wear, which was Shinto-inspired. It truly was a man's outfit, as it featured:
Shirabyōshi wore the trademark white facial make-up that would centuries later come to be associated with geisha, completely covering their face and neck and painting new eyebrows higher on the forehead. Their hair was rather simple: it was long (sometimes nearly to the floor) and pulled back into a loose ponytail secured with a ribbon called a takenaga.
Shirabyōshi songs were mostly based on Buddhist prayers. The songs were usually slow and rhythmic, with great meaning in the words. They also would sing imayo songs, which were poems using images of nature to convey meanings of circumstances in their lives. Trademarks of their music included their voices, the drum and the flute.
