Kumonryu has the characteristic of German carp (Doitsugoi in Japanese) with almost no scales, and is a variety with intense black pattern across the white body. Unlike the utsurizumi found in Showa-sanshoku, it is characterized by a pattern that looks like black clouds are freely rising from the body. It is named Kumonryu from the legend that the dragon becomes a cloud and rises to the sky, and when it has red imprints, it is called Beni-kumonryu.
The ink pattern of this variety is very easy to change, and when the water temperature is high, the ink pattern sinks into the white body, and when the water temperature is low, it gushes out, so it can be said that you can enjoy the change of the pattern.
