Each year on May 5, families in Japan and Hawaii celebrate Children’s Day. Known as Kodomo no Hi in Japanese, this is a day to honor the health and happiness of children.

Around this time of year, you may see colorful streamers of koi, or Japanese carp, hanging in front of homes and throughout neighborhoods. These streamers, or koinobori, are symbols of the hope that children will grow up healthy and strong.


Boys’ Day to Children’s Day
Since girls have their own day of celebration on March 3, it’s natural to assume that there’s a Boys’ Day, too. That was the case up until 1948, when the Japanese government changed Boys’ Day to Children’s Day to lift the spirits of the people after World War II.

A symbolic fish
The koi is not only Japan’s national fish, it’s an important part of the culture. They swim against the current and are regarded as resilient creatures that embody courage, strength, and success through perseverance. Koi can also grow very large and live long lives, symbolizing vitality and longevity.

In Buddhism, koi is a sign of courage and represents fearlessness while making one’s way though “an ocean of suffering.” Their slow, graceful movement convey peace and tranquility.

Let your fish flag fly
Traditionally, koinobori were displayed on a pole with a yaguruma, or a pair of arrow-spoked wheels topped with a ball-shaped spinning vane. A black koi representing the father of the household flies at the top of the pole followed by smaller red koi to represent the eldest son and additional blue, green, purple, and orange flags for subsequent sons. However, over the years, the symbolism evolved to the red koi representing the mother and the rest of the flags representing the children.

These days, there seems to be more creative freedom when it comes to koinobori. It doesn’t matter what color they are, what kind of material they’re made of, or if they’re big or small. What matters is that they make you happy.
