Chinese Carp Legend and Koi Symbolism

One of the best-known stories associated with carp comes from China: a carp that successfully swims upstream and passes the Dragon Gate is transformed into a dragon. Because the fish succeeds by pushing against a difficult current, the story became associated with perseverance, endurance, ambition, and success after hardship. The legend later influenced carp symbolism in Japan as well.

Koi Symbolism in Japan

In Japan, carp are closely associated with strength, perseverance, healthy growth, and success. Around Children's Day on May 5, families and communities display carp-shaped streamers called koinobori. The custom is connected to the older Chinese legend of a carp overcoming a powerful current and becoming a dragon. Koinobori are therefore commonly used to express hopes that children will grow strong and overcome difficulties.
