Carp streamers (koinobori) are traditional Japanese decorations displayed outside homes from mid-April to early May.
They are used to celebrate Children’s Day on May 5 and to wish for children’s healthy growth and success.
Meaning
The carp in koinobori comes from the Chinese legend of Longmen (Dragon Gate legend).
In this story, a carp swims upstream against strong currents and becomes a dragon.
Because of this, koinobori symbolize strength, perseverance, and success in life.
Structure
Koinobori are usually made up of five colors: blue, red, yellow, white, and black.
These colors are believed to protect against evil.
Each carp represents a family member:
- Black carp: father
- Red carp: mother
- Other colors: children
History
Koinobori became popular during the Edo period.
It originally started as a samurai tradition to celebrate boys’ growth.
During Tango no Sekku, families displayed flags and banners.
Over time, these decorations evolved into carp-shaped streamers among common people.
