Doitsu Koi Type

Doitsu Kohaku

DOITSU KOI TYPE -- Doitsu Koi are Japanese koi crossbred into almost all varieties of Nishikigoi. Doitsu are display the characteristics of the German “leather” carp with no scales at all or with the German “mirror” carp having large scales only along both sides of the dorsal fin or with large scales along the dorsal fin and also along the lateral line on both sides of the koi.



Doitsu koi have been crossbred in Japan for most all of the classes and typically compete against scaled Japanese koi in the same class unless there is a special Doitsu class. Doitsu koi can easily have sharp kiwa due to not having scales so scaled koi are given the difficulty advantage in judging. All judging points being equal, scaled koi will beat Doitsu koi.

There is a Doitsu version of almost every variety; Doitsu Kohaku, Doitsu Sanke, Doitsu Yamato Nishiki, and Doitsu Hariwake just to name a few. Doitsu Koi are to be viewed for the orderliness of scale arrangement and the absence of unnecessary scales. Each Koi should have the features characteristic of its own original variety.
