• Lake Nojiri is situated in the northern part of Nagano Prefecture, and Tategahana Site is located on the west coast of the lake. This site has been excavated ten times during the period from 1962 to 1987, and these excavations have recovered many Paleolithic artifacts associated with fossil bones of Palaeoloxodon naumanni (Naumann's elephant) and Sinomegaceros yabei (Yabe's giant deer) from the Upper Pleistocene Nojiri-ko Formation.Paleolithic artifacts and big game fossils were continuously recovered from the Upper Nojiri-ko Member I down to near the base of the Lower Nojiri-ko Member III. The paleolithic artifacts, which coexist with big game fossils, are made of stone, bone, and wood.There are two toosl-making techniques within this range. One of them, belonging to the Paleolithic tradition, is characterized by bone tools and trapezoid flakes laid down during the depositional epoch from the Lower Nojiri-ko Member III up to the Middle Nojiri-ko Member III. The other is characterized by lengthwise flakes laid down during the depositional epoch from the Middle Nojiri-ko Member III up to the Upper Nojiri-ko Member I (about 24, 000y.B.P.).We propose to name these two industries the "Nojiri-ko Culture". This culture is characterized by tools made of big game bones.In addition, the "Kill-Site" hypothesis suggested for this site in 1984, is verified on circumstantial evidence: the skull of a Naumann's elephant was uncovered together with a spear-form wooden tool, and ribs of a Naumann's elephant together with a bone cleaver and other bone tools.
