Made across all of Japan (while the majority of the figurines found were on the eastern coast) except Okinawa, there are various styles of Dogū, depending on exhumation area and time period. According to the National Museum of Japanese History, the total number found throughout Japan is approximately 15,000. The purpose of the Dogū remains unknown and should not be confused with the clay haniwa funerary objects of the Kofun period (250 – 538 AD).
