<p>During an ichthyofaunal survey of southwestern Satsuma Peninsula, Kagoshima Prefecture, Japan, a single pompano specimen (748.0 mm standard length, 814.0 mm fork length) was collected by set net at a depth of 20 m on 24 November 2018. The specimen was subsequently identified as <i>Trachinotus anak</i> Ogilby, 1909, having the following combination of characters: dorsal-fin rays VI-I, 18; anal-fin rays II-I, 16; snout profile essentially straight immediately above upper lip; upper lip separated from snout by a continuous deep groove; a narrow band of villiform teeth on lower jaw; teeth on tongue absent; supraoccipital bone thin and blade-like; nasal and lacrimal bones hyperossified; first supraneural bone an inverted "L" shape; first to third ribs hyperossified; no distinct pattern (e.g., blotches or bands) on lateral body surface; and anal-fin lobe yellow, the anterior margin lacking brownish coloration. Because of the superficial similarity of <i>T. anak</i> to <i>T. mookalee</i> Cuvier, 1832, differentiation between the species sometimes requiring dissection, previous Japanese records of <i>T. mookalee</i> were re-examined. <i>Trachinotus mookalee</i> was confirmed as occurring in Japanese waters, but is known only from a single specimen from Miyazaki Prefecture, east coast of Kyushu, southern Japan. <i>Trachinotus anak</i> was previously known only from Taiwan, northern and eastern Australia, and New Caledonia, the present specimen from Kagoshima representing the first record from Japan and northernmost record for the species. The new standard Japanese name "Yokozunamarukoban" is herein proposed for the species.</p>
