Abstract: |
This report explains the distribution of Tridacna shell adzes found in the southern Ryukyu Islands of Miyako and Yacyama. These adzes are considered to be one of the main features of Southern Ryukyu prehistoric culture
they are not found on the northern Ryukyu islands of Okinawa and Amami, or in mainland Japan. Tridacna adzes have a wide, well known distribution in the South Pacific, including Palawan and Tawi Tawi in the Philippines. Are the southern Ryukyu adzes related to them? This paper provides comparative data for such studies.
