Hinamatsuri, also called Doll's Day or Girls' Day, is a special day in Japan. Hinamatsuriis celebrated each year on March 3. Platforms covered with a red carpet are used to display a set of ornamental dolls representing the Emperor, Empress, attendants, and musicians in traditional court dress.More information can be seen at: http://en.wikipedia.org/wiki/Hinamatsuri
