a festival day for children aged seven, five and three.
Note
The Seven-Five-Three-Festival is an event to pray for the growth of children. Girls celebrate the year they become 3 and 7 years old, whereas for boys it's 3 and 5. The children wear pretty clothes or KIMONOs and go to a shrine. There they receive a kind of stick candy called "chitose-ame", (1000-year candy) which signifies longevity.
