A single specimen of the unicornfish Naso tergus Ho, Shen and Chang, 2011 (Perciformes: Acanthuridae), a species previously known only from Taiwan, was collected off Nakano-shima Island, Tokara Islands, Kagoshima Prefecture, southern Japan, therefore representing the northernmost record for the species and first record from Japan. Comparisons of N. tergus with a congener, Naso hexacanthus (Bleeker, 1855), were made and the diagnosis of the former reviewed. A new standard Japanese name “Shinobitenguhagi” is proposed for N. tergus.
