A crangonid shrimp, Argis crassa (RATHBUN, 1899), is reported from Japan for the first time based on the specimens collected from Wakkanai and Usujiri, Hokkaido. The identification is confirmed by the comparison with the Alaskan specimens. The species is characterized by the three acute median spines on the carapace and the presence of a median carina on the first and second abdominal somites.
