Three Court Ladies “san-nin kanjo 三人官女”

Hinamatsuri (雛祭り Hina-matsuri), also called Doll’s Day or Girls’ Day, is a special day in Japan. Hinamatsuri is celebrated each year on March 3. Platforms covered with a red carpet are used to display a set of ornamental dolls (雛人形 hina-ningyō) representing the Emperor, Empress, attendants, and musicians in traditional court dress of the Heian period.
