Shiraho Saonetabaru Cave Ruins (白保竿根田原洞穴遺跡, Shiraho Saonetabaru Dōketsu Iseki) is a paleoanthropological site located on Ishigaki Island of the Yaeyama Islands in Japan.
[1] It was discovered in 2007 when plans for the New Ishigaki Airport were being developed.
[1] Remains of human heads, feet and arms were found, in all 9 bone fossils, by the Okinawa Limestone Cave Association between 2007 and 2009,[2] and three human samples were dated to between 20,000-16,000 years before present.
[3] In the ruins were also found bones from wild boar and birds (one animal bone calibrated at 12,000 BP[3]), while during the three months in 2011 were discovered approximately 300 human bones from the stratum between 24,000-20,000 years old.
[6] Due to the skeletons' postures, the site has been confirmed as the first graveyard in the Paleolithic age in Japan.
