Le Paléolithique supérieur du plateau de Musashino et les hauteurs de Tama aux alentours de Tokyo

Abstract

The Upper Paleolithic at the region of Tokyo that itself called also the Japanese Preceramic age that possesses a large number of excavations and those studies during the dawn of Paleolithic study in this country. The Preceramic age or the Upper Paleolithic has been raised the curtain by the discovery of a piece in obsidian, in 1949, in the loam of Kantô, at Iwajyuku site. We explain above, on the stratigraphy, the chronology and the situation and the evolution of site around Tokyo. It is a region to the highest density of the Upper Paleolithic sites in the archipelago of Japan and the systematic excavation according to the stratigraphy of loam formation has been done for the first time in the country. The authentic chronology has been proposed to the years 60s that based on the discovered lithic industries on the plateau of Sagamino and Musashino. This chronology was used for a long time that it made a role like a norm for the whole country. Not only, after again an accumulation of the research until the present, we understand the different periodic activities between the Tama hills, the plateau of Musashino, the plateau of Sagamino, the North of Kantô district and the plateau of Simôssa. Of course, there is a complex circumstance that the apparition and the disappearance of various types of lithic instruments are different, and every type tools are not universal around Tokyo area, in the district of Kantô. The final of Upper Paleolithic on the archipelago of Japan divides extensively in two parts East-west that the East of Japan is characterized by the well-organized aspect microlithic tendency and the west is characterized by the trend of microlite, trapeze and tool on transverse blade. In such general tendency, the region of Kantô is located therefore in the center on the archipelago of Japan that it showed sets of every different time.
