Imported originally from Germany, the top quality Japan breed of koi would have to be the Doitsu Koi. Undergoing centuries of specific selective breeding gave the Doitsu a wide variety of contrasting colors in black, white and red. An arrangement of distinct mirror-like scales following the dorsal ridge of the back. This is why the Doitsu is commonly known as the mirror-scale koi.
Often known by breeders as AAA grade koi, the highest rating that these fish can get. These high quality Doitsu koi can turn your Japanese koi pond into a showcase you will be proud to show off to your friends.
