A new nephropid lobster, Hoploparia kamimurai new species is described from the Lower Cretaceous Ishido Formation (Barremian), Gunma Prefecture, central Japan. Two species of glypheid lobsters, Glyphea yoshiakii new species and Glyphea sp. were obtained from the Lower Cretaceous Arida Formation (Barremian), Wakayama Prefecture, southwest Japan and the uppermost Jurassic to lowermost Cretaceous Mitarai Formation (Tithonian–Berriasian), Gifu Prefecture, central Japan, respectively. These species are the first records of the fossil Glypheidae from Japan.
