Koi not included in the varieties mentioned so far are grouped as "Kawarimono." They are "Karasu-goi (crow carp, with coal black body)," "Hajiro (literally 'white wings' for crow carp whose pectoral fins are white at the tip)," "Kumonryu (German Koi of Hajiro strain with white head)," "Ki-goi (yellow carp)," "Cha-goi (brown carp)." "Matsuba (literally 'pine needles)," and "Beni-goi (crimson carp)," etc. You will also find the Akame Kigoi (red eyed Kigoi) in this group.
They have been produced only in small numbers, and large-size Kawarimono are even fewer. They are appreciated above all by their originality or unconventionality. The rarer they are encountered even with active search, the higher is their value.
