A single specimen (130.0 mm standard length: SL) of Platyberyx mauli Kukuev, Parin and Trunov, 2012, collected at 452–453 m depth off Shizugawa Bay, Miyagi Prefecture, Japan, is the first record of the species from the Pacific Ocean. Previously reported only from the eastern central Atlantic, P. mauli is characterized by the following combination of characters: dorsal-fin rays 28 (28 in present specimen); anal-fin rays 17 (17); pectoral-fin rays 17 or 18 (18); total vertebrae number 33 or 34 (34); head length 30.4–33.9% SL (30.5% SL); body depth 45.6–52.2% SL (46.3% SL); prepectoral length 34.2–35.3% SL (34.2% SL); dorsal-fin base length 75.4–79.1% SL (76.1% SL); ventral caudal spur absent; procurrent rays cylindrical; gill rakers stout, rounded, with many small bristles, especially near tip and midway along each raker; jaw teeth in multiple rows anteriorly; posterior margin of upper jaw extending nearly to posterior margin of orbit; dorsal pharyngeal papillae multifid; conspicuous multifid papillae throughout inside of mouth cavity. The new standard Japanese name “Shamoji-yaegisu” is proposed for the species. Additionally, a single specimen (176.9 mm SL) of Platyberyx andriashevi (Kukuev, Parin and Trunov, 2012), collected off the Pacific coast of Hokkaido, represents the first record of the species from that region. A key to the six species of Caristiidae currently known from Japan is provided.

New distributional records of forty-five fish species off the Pacific coast of Tohoku District, northern Japan are reported, based on specimens trawled by the R/V Wakataka-maru (Japan Fisheries Research and Education Agency) during surveys in autumn of each year from 1995 to 2019. The records include northern distribution range extensions of 19 species, distribution gaps filled for 17 species, and northern and southern limits along the Pacific coast of Japan for eight and one species, respectively. Twenty-seven species were recorded off Tohoku District for the first time. In addition, taxonomic notes for each species, including some meristic and morphometric data from the collected specimens, are also provided.
