Previous surveys of fishes of Yonagunijima Island, the westernmost island of Japan, have recorded a total of 603 fish species (104 families). Field sampling was recently carried out at the island resulting in an additional 30 species recorded from Yonaguni-jima Island for the first time, plus a further 7 species now represented by voucher specimens, having been previously recorded from Yonaguni-jima Island only by underwater photographs. In addition, we have collected two adult specimens of Scarus rubroviolaceus Bleeker, 1847 (family Scaridae), as the species was available only as a juvenile specimen in previous reports. We have also successfully rereported with a fresh-colored specimen’s photograph of Pterois radiata Cuvier, 1829 (the family Scorpaenidae), which was previously recorded without any photographs. Color photographs of all these additional species are provided. The number of fish species from Yonaguni-jima Island now totals 633 (105 families).
