Hina Ningyo are traditional Japanese dolls displayed during the Hinamatsuri festival, also known as Girls' Day, celebrated on March 3rd. These dolls represent the Emperor, Empress, and their court, often dressed in elaborate clothing. Families with daughters display them on a tiered platform, symbolizing wishes for the health and happiness of their girls. The dolls are typically made of materials like cloth and paper, and they are often adorned with intricate details. The practice of displaying Hina Ningyo dates back to the Heian period, and it is believed to bring good fortune and protect girls from misfortune.
