 It was renamed "Kodomo no Hi" (Children's Day) and changed to include both boys and girls.Before this day, families raise the carp-shaped "koinobori" flags (carp because of the Chinese legend that a carp that swims upstream becomes a dragon, and the way the flags blow in the wind looks like they are swimming), one for each boy (or child), display a Kintarō doll usually riding on a large carp, and the traditional Japanese military helmet, "kabuto".Kintarō and the "kabuto" are symbols of a strong and healthy boy.
