Twenty-seven individuals of Lateolabrax latus (165.7–691.5 mm in total length), a species normally associated with a rocky offshore habitat in southern Japan, were collected from July to October 2009 in the lower reaches of rivers in Yaku-shima Island, Kagoshima Prefecture, southern Japan by hook and line. Furthermore, schools of immature individuals were observed around hard structures (including rocks and tetrapods) or in riffle zones in the rivers, L. latus clearly making active use of river environments in Yaku-shima Island during its life history. Because a detailed morphological description of the species has not been given since its original description, the specimens from Yakushima Island are described and compared with other congeners. Characters of the former agreed closely with the original diagnosis of L. latus. Some individuals less than 200 mm standard length had tiny scattered spots, smaller than those on other congeners, on the region above the lateral line. Specimens from the Ambo River represent the southernmost record of the species.
