During Kodomo No Hi (Children's Day), families raise colorful carp-shaped "Koinobori" flags, one for each member of the family. The largest and uppermost flag represents the father, followed by the mother, and small carp to represent children.
Children's Day is a Japanese national holiday which takes place annually on May 5, the fifth day of the fifth month, during the Golden Week period. It is a day set aside to respect children's personalities and to celebrate their happiness. To expel evil spirits and celebrate the future of their sons, families hoist koinobori (cloth carp streamers) from balconies and flagpoles.
Kintarou (金太郎) is the childhood name of a hero of the Heian period, famous for his strength as a child. It is said that Kintarou mounted on a bear, instead of a horse, and played with animals in the mountain when he was a young boy.Some children may also take shyobuyu (a bath with floating iris leaves), and eat kashiwa-mochi (a rice cake wrapped in an oak leaf ) and chimaki (a dumpling wrapped in bamboo leaves). Carp, samurai, irises, oak trees, and bamboos all symbolize strength.
