Koi fish, also known as Nishikigoi, is a species of carp that was first domesticated in China over 2,000 years ago. The fish was later introduced to Japan in the 17th century, where they quickly became popular among Japanese fish breeders. Over time, the Japanese developed a number of different varieties of koi fish, each with its own distinctive colors and patterns.

In the early years of their introduction to Japan, koi fish were primarily used as a source of food. However, their striking appearance and graceful movements soon captured the attention of Japanese artists and storytellers, who began incorporating fish into their works.

Koi fish are also often associated with good fortune, wealth, and prosperity. In traditional Japanese homes, it is common to find artwork featuring koi fish, as it is believed that the fish brings good luck and financial success.
