Throughout Japan, families who have girls are displaying their doll collections for some days to celebrate Hina Matsuri.
The dolls displaying starts a week or two before the festival, and is done by the mother of the girl. Then the dolls should be closed on the same day of March 3rd, or at the latest the next day. As one legend says, if the dolls are displayed more than 3 days after the festival, the girl can not marry or she will marry later in life.
