The History of Children's Day?

Children's Day has evolved from ancient traditions into one of Japan's most beloved national holidays. Its roots stretch back over a thousand years to the Nara Period (710–794), when Japan adopted Chinese seasonal festivals known as sekku. May 5 became known as Tango no Sekku, the "Boys' Festival", while March 3 was celebrated as the "Girls' Festival".

During the Edo Period (1603–1868), Tango no Sekku became an important samurai celebration, honoring boys' growth, strength and the hope that they would grow into brave, successful men. Families would display samurai armor, helmets, and warrior dolls to symbolize courage and protection. Outside, they raised carp-shaped streamers, inspired by Chinese legend: a carp that swims upstream transforms into a dragon, symbolizing perseverance and achievement.

After World War II, in 1948, Japan's postwar government redefined the holiday under the new constitution as Children's Day, making it a national holiday for all children, regardless of gender. The change reflected democratic ideals of equality, peace and appreciation for children's happiness and families' well-being.

Today, Children's Day marks the final day of Golden Week, a time of family gatherings, festivals, and outdoor celebrations. Carp streamers, samurai dolls and the traditional sweet kashiwa mochi remain enduring symbols of love, hope, and strength for future generations.
