Straight from wikipedia “The Japanese Doll Festival (??? Hina-matsuri?), or Girls’ Day, is held on March 3, the third day of the third month. Platforms with a red hi-m?sen are used to display a set of ornamental dolls (??? hina-ningy??) representing the Emperor, Empress, attendants, and musicians in traditional court dress of the Heian period.”
