A range extension to Japanese waters is recorded for three crangonid shrimps: Lissosabinea indica (De Man, 1918) previously only known from the Philippines and Indonesia; Parapontocaris levigata Chace, 1984 known from the Indo-West Pacific up to Taiwan; and Rhynocrangon sharpi (Ortmann, 1895) known from the northern North Pacific including the Far East Russian coast of the Sea of Japan. The first two species are the only members of their genera recorded from Japan. Diagnosis and illustrations are given for L. indica and P. levigata for the species recognition. Rhynocrangon sharpi is fully redescribed and illustrated, because there is no detail description of this species.
