We conducted SCUBA-based surveys of the larval and juvenile fish fauna in reef and seaweed areas in the inshore region of Usujiri, Hakodate, along the Pacific coast of southern Hokkaido, Japan, from 2019 to 2020. A total of 100 species in 10 orders and 44 families were identified based on morphological observations and DNA barcoding analyses of the cytochrome c oxidase subunit I (COI) gene. Of these species, two specimens of the labrid, Pseudolabrus sieboldi Mabuchi and Nakabo, 1997, one specimen of the cottid, Cottus hangiongensis Mori, 1930, two specimens of the blennid, Petroscirtes breviceps (Valenciennes, 1836), and one specimen of the gobiid, Pterogobius zacalles Jordan and Snyder, 1901, represent the first records of these four species in the study area. In addition, three specimens of the Stichaeid, Lumpenopsis pavlenkoi Soldatov, 1916, represent the first records captured during juvenile stages of this species, and one specimen of the pleuronectid, Lepidopsetta mochigarei (Snyder, 1911) represent the first juvenile captured in Usujiri of these species. The fish list is also added in this report.
