Koi - The History

A brief journey in time

The history of Koi is as mysterious as they are beautiful. Popular conviction would have us believe that Koi are indigenous to Japan. In fact, they are even mistakenly called “Japanese Goldfish”

Just for the record “What is the difference between goldfish and Koi?“ Goldfish and Koi are both selections of carp, but from two different families. Goldfish are mutations from Crucian Carp (Carassius carassius) and Koi are from common carp (Cyprinus carpio).

So if they did not originally come from Japan, where then? They are believed to originate from eastern Asia, in the Black, Caspian, Aral Seas and China. Carp fossils have been discovered in South China dating as far back as 20 million years ago. Some varieties are known for their hardiness, which records claim can live for long periods of time if simply wrapped in wet moss continuously kept damp.

The earliest written records of Koi, or Nishikigoi, (Japanese for "brocaded" carp) were first described in writing from a Chinese book written during the Western Chin Dynasty, around 265-316 A.D. At that time they were described as white, red, black and blue.

Koi are believed to have been introduced to Japan with the invading Chinese and a first account of them being kept by an emperor in Japan, apparently dates Back to AD 200.

Emperor MeijiNot much is known, or has been recorded, as to what happened to Koi between the 2nd to the 17th century and it is still a mystery, but many suspect Koi gradually spread through the orient, possibly by way of trade caravans to and from the middle east.

From this time the history of Koi moves forward to the 17th century, when rice farmers of Yamakoshigo, a village in the Niigata prefecture on the northwestern coast of mainland Japan, started raising magoi (black carp) to supplement their winter diet. They raised these carp in the ponds they used to grow their rice paddies.

About 200 years ago, one of the farmers noticed a carp with some red color. Color mutations began to appear between 1804 and 1830 with red, white, and light yellow becoming the first colors to appear. (Perhaps the first Kohaku and Ogon) Some of the farmers started separating the fish that had different coloration's, and breeding them together. By the late 1880s modern day color patterns were fixed and the hobby of Koi breeding and collecting began in earnest.

The interest in this pastime grew and more color variations were developed. It wasn't until 1914 that some of the most beautiful varieties were shown at an exposition in Tokyo. Some of these colored carp were presented to Crown Prince Hirohito.

Today Koi are bred in every country and considered to be the most popular fresh-water ornamental pond fish. Nishikigoi is now called "living jewel" "Kokugyo" and "king of ornamental fish." Nishikigoi represents Japanese culture. It is also loved and appreciated by the name of "Koi" all over the world.
