An invasive freshwater shrimp of the genus Neocaridina Kubo, 1938 (Decapoda: Caridea: Atyidae) was collected from the Tomoe River of the Boso Peninsula, Tateyama City, Chiba Prefecture, eastern Japan. We compared the morphological characteristics and mitochondrial DNA sequence variation of the specimens with those of other Neocaridina species. In particular, we assessed the mitochondrial DNA region encoding the NADH dehydrogenase subunit 2 [ND2] gene and the region encoding the NADH dehydrogenase subunit 5 [ND5] gene. Our specimens are most likely to be Neocaridina davidi (Bouvier, 1904), a species native to mainland China. This species may have entered Japan through intentional disposal or accidental escape from aquaria.
