Children's Day (Kodomo no Hi) – May 5, 2023

Kodomo no Hi, or Children’s Day is a Japanese holiday celebrated on May 5 every year. It is meant to respect children’s individuality and to celebrate their happiness. Kodomo no Hi was deemed a national holiday in 1948 by the Japanese government but has been celebrated for much longer. On this day, families raise ‘koinobori,’ or carp-shaped windsocks, with different colored carps for different members of the family. Before switching over to the Gregorian calendar, the holiday was celebrated on the fifth day of the fifth moon in the Chinese calendar.

History of Children's Day (Kodomo no Hi)

Kodomo no Hi was first celebrated as Tango no Sekku and was one of the five annual ceremonies held at the imperial court, called Gosekku. It is the Japanese equivalent of Double Fifth and was celebrated on the fifth day of the fifth moon in the Chinese calendar. The date was moved to May 5 when Japan switched over to the Gregorian calendar.

It is believed that Tango no Sekku was first celebrated during the reign of Empress Suiko, the 33rd monarch of Japan. It was first assigned to the fifth day of the fifth month after the Nara period in Japanese history. Until 1948, Tango no Sekku was known as Boys’ Day, with a separate Girls’ Day. However, on March 3, 1948, the Japanese government declared that this day was to be a national holiday, renamed Kodomo no Hi, meant to celebrate the happiness of all children, regardless of gender, and to express gratitude for mothers.

On this day, families raise koinobori, or carp-shaped windsocks, with a black carp to represent the father, a red or pink carp to represent the mother, and one green, orange, or blue carp for each child in the family. This tradition is based on a Chinese legend of a carp swimming upstream and becoming a dragon.
