Every year on May 5th, people in Japan celebrate a festival known as Children's Day. This festival celebrates the happiness of children and mothers across the country. It is a national holiday for everyone in Japan.

Children’s Day probably began as a festival for boys around AD 600. People flew flags shaped like a fish called a carp. The carp is a symbol of strength and health. Each boy had his own flag, and the oldest boy had the biggest flag. People still fly carp flags today. In 1948, the Japanese government changed the festival for both boys and girls.

People in Japan do many things on Children’s Day. They eat special food, such as rice cakes wrapped in oak leaves. They also take baths in hot water with iris leaves. These leaves are said to be good for a person's health. But the children in Tokyo get something extra special. They compete in the Kids’ Olympics on Children’s Day. There is a torch relay and races for kids and their parents. So before you’re too old, plan a trip to Japan to celebrate Children’s Day and have fun being a kid!
