The art of the geisha began in 17th century Japan but truly developed in the late 19th century. Geisha were originally men who cross-dressed, but later became exclusively women. A geisha's art includes musical performances, dancing, tea ceremonies, and witty conversation. Young geisha, called maiko, undergo training for several years. They live communally and are in debt to the okiya head until their training is complete and debts paid. While once very common, there are now only around 1,000 practicing geisha in modern Japan due to changing social and economic conditions after World War II.
