Caenorhabditis japonica is a species of nematodes in the genus Caenorhabditis. Its genome was sequenced by the Genome Center at Washington University. This gonochoristic species is found in the 'Japonica' group, the sister clade to the 'Elegans' group, in the 'Elegans' supergroup.

In the wild, this species is found non-parasitically associated with the burrower bugs Parastrachia japonensis (Heteroptera: Cydnidae)[1] and may be able to enter the dauer stage regardless of food and crowding conditions.[2][3]
