PlaziCarboniferous and Permian carbonate sequences in Japan are most completely preserved in the Akiyoshi Limestone in the Akiyoshi Terrane (Permian accretionary complex), Southwest Japan. The studied Sakmarian to lower Kungurian sequence is biostratigraphically divided into six zones: Globifusulina nux Zone and Globifusulina krotowi Zone (Sakmarian), Chalaroschwagerina vulgaris Zone (lower to middle Artinskian), Paraleeina magna Zone (upper Artinskian), Pamirina leveni Zone (uppermost Artinskian), and Miselllina dyhrenfurthi Zone (lower Kungurian) based on stratigraphic distribution and species composition of the fusuline faunas in Akiyoshi. These zones are compared and correlated to those in the Cisuralian stratotypes of the South Urals and Tethyan regions. Many fusuline species common in Akiyoshi and South Urals are discernible in the Sakmarian, and the Tethyan faunal elements become dominant in the Artinskian. Foraminifers consist of 117 species assignable to 53 genera in this study. Five fusuline species newly proposed are Chenella rhomboides, Praemisellina minensis, Chalaroschwagerina compacta, Paraleeina cubiformis, and Paraleeina toriyamai.
