Discovery of hyoliths from the Gedinnian bed of the Lower (to Middle?) Devonian Fukuji Formation in central Japan constitutes the first occurrence of this group from Japan. The operculum shows features much in common with Joachimilites MAREK, 1967 that was previously known only from the Ordovician bed in Bohemia. It now appears that the genus ranges from the Ordovician (Caradocian) to Early Devonian. The Fukuji species, Joachimilites fukujiensis, is described as new.
