Category:Turtle-back tombs

English: Turtle-back tombs, surrounded by an omega-shaped ridge, are common in Japan's Okinawa Islands and in some coastal areas of China's Fujian Province (e.g., around Quanzhou). J.M.M. de Groot has a detailed discussion of them (as seen around Amoy, i.e. Xiamen) in Volume III of "The religious system of China", pp. 942-943, 1082-1083
