Mammalian bone remains amount to 231 kg. were found at the rockshelter site of Tochibara, Kita-Aiki-Mura, Minami-Saku-Gun, Nagano Prefecture (The Earliest Stage of Jomon Period, about 8, 400 years B.P.) . The fauna of mammalian remains was composed of 22 species belonging to 6 orders. They were Crocidura dsinezumi, Mogera wogura, Macaca fuscata, Lepus brachyurus, Sciurus lis, Petaurista leucogenis, Eothenomys andersoni, Eothenomys kageus, Microtus montebelli, Apodemus speciosus, Apodemus argenteus, Selenarctos thibetanus, Canis lupus, Nyctereutes procyonoides, Vulpes vulpes, Martes melampus, Mustela sibirica itatsi, Meles meles anakuma, Lutra lutra, Sus scrofa leucomystax, Cervus nippon and Capricornis crispus crispus. Based on the number of excavated mandibula of medium and small-sized mammals, the more abundant species were Petaurista leucogenys, Lepus brachyurus, Martes melampus, Apodemus speciosus and Sciurus lis (Table 1) . Based on the number of the excavated calcaneus and talus of large mammals, it was estimated that the most important game at that time was Cervus nippon and the next was Sus scrofa leucomystax (Table 2 & 3) . They were found throughout all over the horizons yielding mammalian bones. Relative aboundances of the big games based on the total number of calcaneus and talus were as follows: deer, 9.3; monkey, 3.0; wild boar, 2.3; serow, 1.3; black bear, 1.0.
