Koinobori are traditional wind streamers displayed at Japanese homes to celebrate Children’s Day on May 5th every year. This day is especially recognized as a celebration of boys’ growth, and koinobori are widely cherished as a symbol of this occasion. These carp-shaped streamers carry deep historical and symbolic meanings, making them popular as gifts and commemorative items, often passed down through generations. Today, let’s take a closer look at koinobori.
The Origin and History of Koinobori
The origin of koinobori can be traced back to an ancient Chinese legend. In this tale, a carp swims upstream along the Yellow River and transforms into a dragon after leaping over the Dragon Gate waterfall. This story came to symbolize perseverance and overcoming hardships, with the image of the carp swimming up the waterfall representing the hope for success and advancement in life. The legend eventually made its way to Japan, where koinobori began to be displayed as a wish for boys to grow strong and achieve great things, just like the carp in the legend.During the Edo period, the custom of displaying koinobori to celebrate children’s growth spread mainly among the samurai class. Over time, the practice became popular among the general population as well, and it became a widespread tradition to display koinobori on Children’s Day, as it is today.
When to Display Koinobori
There are no strict rules about when to display koinobori, but they are generally put up around the spring equinox and remain until May 5th, Children’s Day. Therefore, the main display period is from late March to early May, when they are most commonly seen. While many families take them down shortly after May 5th, some regions continue to display them until around May 10th. In some cases, families enjoy keeping them up for a longer period as a seasonal tradition to be enjoyed.
Koinobori and the Community
Koinobori are not just a family tradition but also an important part of community events. In some areas, multiple households collaborate to display large koinobori together, and festivals themed around these streamers are held throughout Japan. These events foster a sense of unity among community members and play an important role in passing down cultural traditions to future generations.
