At this time of the year there are displays for the Japanese Doll Festival, Hinamatsuri or Girl’s Day, which is celebrated on March 3. The platforms display ornamental dolls. On top, there are the Emperor and the Empress, next their attendants and then the musicians. All are dressed in the court dress of the Heian period (794-1185).
In February, the dolls are already on display but need to be taken down no later than March 4. Leaving it past might lead to a late, or even worse, no marriage for the daughter.
These gorgeous window displays can be viewed at Yukiko Hanai, Aoyama dori, Tokyo.
