The Tokyo bitterling (Pseudorhodeus tanago) is a temperate freshwater ray-finned fish belonging to the family Acheilognathidae. This fish is endemic to the island of Honshu in Japan.

The species was first described as Rhodeus tanago by Shigeho Tanaka in 1909. It is widely known as Tanakia tanago, although a 2014 study suggests it is genetically distinct from other Tanakia species, and warrants placement of it in the monotypic genus Pseudorhodeus.
