Mr. Takeo Kuroki, founder
and first chairman of Zen Nippon Airinkai, defines Nishikigoi as follows: Nishikigoi is a generic term for Koi which have colors
and patches and are raised for appreciation.
The historical origins of Nishikigoi are as
follows: 200 years ago in Niigata Prefecture's Yamakoshi Village and the surrounding areas, the farm-raised edible
Koi started mutating. Some of the breeders noticed, on rare occasions, Koi with red and yellow
patches. From
this point they started to breed these colored Koi. In the Meiji
Era, the phrase beautiful Koi was widely used and made the rounds among the people and so varieties
such as Kohaku were developed.
The Taisho Exposition was held in the 3rd year
of the Taisho Era (1914), which is when Nishikigoi started to become more
popular in society. The varieties produced and established in the Taisho
Era are Taisho Sanshoku, Shiro Utsuri, Ki Utsuri, and Asagi. In the Showa
Era (1925) Showa Sanshoku, Kin Uchiwa, Gin Uchiwa, and Kin Kabuto
were produced.
After the war, breed improvement was temporarily
suspended, but with the introduction of Nezu Ogon, the Hikarimono variety
was produced leading to the golden age of Nishikigoi. The creation of the
Doitsu lineage with varieties such as Shusui, crossbreeds of German Carp
and Nishikigoi, and of the Ogon variety, played a prominent role in todays
Nishikigoi development.
The photo below shows the Koi Gene Tree. It represents the necessary crosses
that were made in order to produce the Koi we see today. Some Koi varieties were
produced from rare mutations.
There are over 100 different varieties of
Nishikigoi, including the fixed variety and their variations. INPC specifies
26 as fixed varieties and other crossbred varieties are called variations.
Below are the accepted varieties that are considered
fixed. Click on the Gallery link to view ALL varieties that are
available in the world of Koi today.
