Abstract

^<14>C ages of 9 samples were measured with Tandetron Accelerator Mass Spectrometry of Dating and Materials Research Center, Nagoya University. Those samples were recovered from the sea floor off Yonaguni-jima and the coast of it. ^<14>C ages reveal younger ones than 700 year from now. Therefore, the artificial pyramidal configuration of the Iseki Point off Yonaguni-jima may have been made older than 6,000 year on shore.
