Contrary to popular western ideas, Japanese geisha is not a common word to describe women's notoriety. The word literally means "artist", and geisha is the traditional occupation of well-trained professional women. Geisha's singing, dancing, playing music, rich historical knowledge and ability to deal with current affairs are necessary skills for dialogue and creating a relaxed and entertaining atmosphere. The unique skills of Japanese culture include the ability to perform tea ceremony, and even skilled flower arrangement or calligraphy. Geisha are not prostitutes.
