Meaning & origin

What does Koi mean?

Koi means “Carp”.

Koi is the Japanese word for carp, especially familiar in English through the colorful fish kept in ornamental ponds. The patterned varieties are associated with nishikigoi, a term describing ornamental or brocaded carp. As a word name, Koi therefore has a direct aquatic and Japanese-language connection.

Carp also appear in Japanese cultural imagery, including the carp-shaped streamers used for Children’s Day. Those associations can suggest perseverance or strength, but they are symbolic meanings rather than the literal translation of the animal word. Japanese has other words pronounced koi, including one associated with love, and the written characters distinguish them. Families drawn to carp can explain Koi through the fish and its cultural associations, keeping the separate word for love distinct.
