Two species belonging to two goneplacid genera from the Miocene of Japan are herein described. Carcinoplax granulimanus Karasawa and Inoue, 1992, from the Middle Miocene (Serravallian) Osaki Formation of Tanegashima, is assigned to Entricoplax Castro, 2007. The revised diagnosis and description are provided for this species. Exopheticus cf. hughi (Rathbun, 1914) is recorded from the Lower Miocene (Burdigalian) Kurosedani Formation of central Honshu. Both genera are recorded for the first time from the Miocene of Japan.
