One specimen of syngnathid, Hippocampus mohnikei (Bleeker, 1853), eight specimens of callionymid, Repomucenus curvicornis (Valenciennes, 1837), two specimens of callionymid, Repomucenus valenciennei (Temminck and Schlegel, 1843), 12 specimens of paralichthyid, Tarphops oligolepis (Bleeker, 1858), and 17 specimens of monacanthid, Rudarius ercodes (Jordan and Fowler, 1902) were collected from inshore Usujiri, the Pacific coast of southern Hokkaido, Japan. These specimens of H. mohnikei, R. valenciennei, T. oligolepis, and R. ercodes represent the northernmost records of these species in the Pacific Ocean, and these of R. curvicornis represent the first records of these species from the study area.
