Abstract :A brachiopod fauna, consisting of 26 species in 20 genera, is described from the Upper Permian (Lopingian) Takakurayama Formation of the Takakurayama area in the Abukuma Mountains, South Kitakami Belt, northeast Japan. This fauna includes two new species, Chonetimella iwakiensis and Chonetinella transversa. The Takakurayama fauna is a Boreal-Tethyan mixed fauna and allied with the Middle to Late Permian brachiopod faunas of North China (Inner Mongolia), Northeast China (Heilongjiang and Jilin), eastern Russia (South Primorye), northeast Japan (southern Kitakami Mountains in the South Kitakami Belt), central Japan (Moribu in the Hida Gaien Belt) and southwest Japan (Mizukoshi in the Hida Gaien Belt). These regions were probably located within a large continuous sedimentary basin on continental shelf or slope bordering the northern and eastern margins of Northe China in the Middle to Late Permian.
