Two Early Carboniferous (late Visean to Serpukhovian) brachiopod species, Echinoconchella sp. and Gigantoproductus sp., are described from limestone floats at Tsuchikurazawa, a tributary of Kotakigawa in the Omi area, central Japan. The occurrence of these brachiopods suggests that the limestones of Tsuchikurazawa, derived from limestone blocks of the Middle to Upper Permian Kotaki Complex, were probably originated from the lowest part of the Ichinotani Formation (upper Visean to Serpukhovian) of the Fukuji area, Hida Gaien Belt or its equivalents. This indicates that the Akiyoshi Terrane including the Kotaki Complex was accreted at the front of the Hida Gaien-South Kitakami-Kurosegawa continental shelf, developed on the eastern margin of North China (Sino-Korea) in the Middle to Late Permian time.
