These flags are called Koinobori, meaning carp flags, which is a traditional decoration to hung it outside the house to wish the boys a successful life. Japanese people display the carp flags from April through early May, for the Children’s Day (May 5th).
In this article, we introduce history, customs, sightseeing spots of Koinobori, and other interesting information such as “why carp?”
History: Why Carps Flying in the Air?
Carp symbolizes advancement and success in life.
There is an old story. Once upon a time, many kinds of fishes tried to swim toward the upstream of a long river named “Koga River”. Although most fishes gave up, only a carp succeeded to reach the upper stream and became a dragon. Since then, carp became to symbolize advancement and success.
It is said the origin of Koinobori, the carp flag, is in Edo period (1603 – 1868 A.D.)
Shogun of Edo period started to raise flags in which carps are drawn. It is to celebrate a new born boy in Shogun’s family. Shogun is the top general of the era. By raising carp flags, a symbol of advancement and success, they prayed for the prosperity of descendants. At the same time, Shogun displayed his power to people by raising great flags of carp.
Then, some other people with power and money begun to imitate Shogun. They also prayed their children’s advancement and success in their lives. Someone added some decorations around the carp flags, other one added other colors, and some others added other types of flags or windsocks in addition to carp flags. This was the origin of Koinobori.
Generally, they’ve raised Koinobori in April to early May. And this custom is called the Boy’s Festival, or it also called “Tango no sekku”.
Design: Typical Pattern of a Set of Koinobori
There are several variations in minor part, a typical pattern of Koinobori is as following.
From the top of the pole down,
- Yaguruma – a pair of arrow-spoked wheels with a ball-shaped spinning vane
- Fukinagashi – flying-dragon streamer (called Fukinagashi) which looks like a windsock
- Koinobori – several carp flags/windsocks that fly beneath the streamer – the most basic set of Koinobori consists of a black Koinobori representing the father, followed by a smaller red Koinobori representing his eldest son. If more boys are born in the household, additional of blue, green and purple/orange Koinobori(s) are added depending on the number of boys.Nowadays, however, other definition of Koinobori set are widely accepted; the red Koinobori came to represent the mother of the family and the other colors and sizes of carp came to represent all the family’s children both sons and daughters. It is said that this change was made after the government’s decree that converted the Boy’s Day (Tango no Sekku) into the present Children’s Day, by which the holiday came to celebrate the happiness of both boys and girls.
Traditionally, there is a song for Koinobori. This song often sung by children and their families at around the Children’s Day (May 5th).
Lyrics of the Koinobori Song
屋根より 高い 鯉のぼり
大きい 真鯉は お父さん
小さい 緋鯉は 子供たち
In English (translation)
Higher than the roof-tops are the koinobori
The large carp is the father
The smaller carp are the children
They seem to be having fun swimming.
