Seven species of decapods are described from the Izumi Group (Upper Cretaceous: Campanian–Maastrichtian) of Hyogo and Osaka Prefectures, central Japan. Archaeopidae, a new family of Retroplumoidea embraces the monotypic Late Cretaceous genus Archaeopus. Hinecaris simplex, a new genus and species is the first record for the axiidean family Axiidae from the Cretaceous rocks of Japan. “Callianassa” (s.l.) masanorii Karasawa, 1998, is re-described and is moved from Callianassidae to Gourretiidae. A re-description is given for Linuparus japonicus Nagao, 1931, and Archaeopus ezoensis (Nagao, 1941). The lectotype for Linuparus japonicus Nagao, 1931, is herein designated.
