Why do the Japanese raise carp kites on Children’s Day?
Children’s Day, May 5th of every year, used to be called Tango no Sekku, or Boys’ Day.
It was renamed in 1948 to Children’s Day to celebrate the happiness of all children and thanks to their mothers. Carps represent social climbing, after a Chinese legend in which a carp that swam upstream became a dragon. Each carp represents a member of the family； the black one the father, the red one the mother, and the last carp the son. More carps are raised for more family members, and in recent years, daughters are also represented.
