Children's Day is a Japanese national holiday which takes place annually on May 5 and is the final celebration in Golden Week. It is a day set aside to respect children's personalities and to celebrate their happiness. On this day, families raise the koinobori, carp-shaped windsock (carp because of the Chinese legend that a carp that swims upstream becomes a dragon and flies to Heaven, and the resemblance of the waving windsock to swimming fish), with a black carp for the father, a red or pink for the mother, and one carp (usually blue, and sometimes green and orange too) for each child. Traditionally, when celebrated as Boys’ Day, the red koinobori was for the eldest son with blue and additional colors for younger brothers.
