Specimens of Gyrodactylus cyprini Diarova, 1964 (Monogenea: Gyrodactylidae) and Dactylogyrus extensus Mueller and Van Cleave, 1932 (Monogenea: Dactylogyridae) were obtained from the common carp Cyprinus carpio Linnaeus, 1758, which was reared in an outdoor pond at the Tamaki Field Station of the Fisheries Technology Institute, Mie Prefecture, Japan. Although G. cyprini is a well-known parasite of C. carpio in the Palearctic and USA and its existence in Japan was implied by the dermatitis examination of exported koi carp from Japan to Thailand, any specimen of G. cyprini has not been recorded in Japan. In addition, I determined some Japanese specimens previously identified as G. kherulensis Ergens, 1974 were also G. cyprini. This study obtained novel geographical records of these monogeneans, along with redescriptions of three monogenean species and molecular data of G. cyprini and D. extensus.
