This diverse grouping encompasses all nonmetallic koi (“Kawari”) that are not included in other categories, although most are named and recognized varieties in their own right.
Among the most popular are single-colored koi of various colors, which can provide a striking contrast to patterned koi in a pond.
This category also includes koi that are predominantly black in color; these are considered to be the koi most closely related to the ancestral Magoi
In addition to koi with standard matt coloration, Kawarimono includes partially scaled (“Doitsu”)and shiny-scaled (“Gin Rin”) varieties.
Rarities—unique koi that do not fit into other groups and whose parentage may be
unknown—also feature in this group.
There is some variation between the koi considered to be Kawarimono in Japan and the standards elsewhere in the world.
