Stone Age relics found in Hokkaido

SAPPORO (Kyodo) Researchers have unearthed well-preserved artifacts dating from the Paleolithic Epoch in Chitose, Hokkaido, local archaeologists said Tuesday.
The Hokkaido Archaeological and Cultural Remains Investigation Center has unearthed about 50 tree roots and some 3,000 stone tools from a 50 meter by 60 meter section of the Kashiwadai-1 archaeological site dating from between 17,000 and 18,000 years ago.
The Old Stone Age people living in the area apparently used the stone instruments, mainly scrapers and other knifelike tools, to cut up the carcasses of animals they hunted in the forest.
The tools resemble ones recovered from Siberian archaeological sites.
