We report six freshwater ostracods from Rishiri Island, Hokkaido, Japan: Cypricercinae sp., Cavernocypris sp.1, Ca. sp.2, Cypridopsis vidua, Candonini sp., and Metacypris cf. digitiformis. This is the first report of freshwater ostracods from this island. We provided brief descriptions of their morphology, presented partial nucleotide sequences for their mitochondrial cytochrome c oxidase subunit I(COI) and/or nuclear 18S rRNA genes, and determined a partial 16S rRNA sequence for the endosymbiotic bacterium Cardinium in some species. A key to six species collected from this island was presented.
