Kohaku

Kohaku is characterized by red imprints across the white body. It is said that various Nishikigoi varieties were born based on Kohaku. Although the body color of Kohaku is a simple color scheme of white and red, the atmosphere created from it is diverse, and it is even said that the viewing of Koi begins with Kohaku and ends with Kohaku.
Kohaku with a clear white background and dark and bright red imprints are considered to be good, and those with a clear boundary (called “kiwa” in Japanese) between the white background and red imprints are considered to be excellent products. There are various variations of the shape of the red imprints, such as “Ni-dan”, “San-dan”, “lnazuma”, and “Maruten” called in Japanese.
