Children's Day in Japan: Carp Streamers and Family Traditions

Children's Day, known as Kodomo no Hi, is a national holiday in Japan celebrated on May 5. It is a day for families to celebrate the well-being, happiness, and personal growth of their children. While the holiday was originally focused specifically on boys, modern celebrations are inclusive of all children.

The Symbolism of Koinobori

The most recognizable sight during this season is the display of koinobori, or carp streamers. These colorful windsock-like decorations are flown on poles outside homes or near rivers. The carp is chosen as a symbol because of its strength and perseverance; in Japanese folklore, carp are said to be able to swim upstream and even climb waterfalls to become dragons.

Typically, the streamers follow a specific order: a black carp (representing the father), a red carp (representing the mother), and smaller blue or other colored carp (representing the children). Seeing these streamers fluttering in the wind is a classic sign that May 5 is approaching.

Traditional Decorations and Foods

In many households, families also display traditional samurai helmets (kabuto) and miniature armor sets. These items are displayed to wish for the children to grow up strong, courageous, and resilient. While these decorations are traditional, many modern families opt for simpler, more contemporary ways to celebrate.

Food also plays a central role in the festivities. A common seasonal treat is kashiwa-mochi, which are rice cakes wrapped in oak leaves. The tradition of eating these stems from the belief that oak trees sprout new leaves before the old ones fall, symbolizing the continuity of family lineages and the healthy growth of the next generation.

How to Observe the Holiday

As a resident or visitor, you will mostly observe Children's Day through the decorations in residential areas and public parks. Many local municipalities and shrines hold seasonal events, exhibitions, or festivals during the first week of May. If you are traveling, look for riverside parks where large-scale koinobori displays are often installed for public viewing.
