We analyzed the obsidian stone tools of the late Paleolithic period in both the old site of the Meiji University Izumi Campus in Tokyo and the Uenodaira Site in Suwa City, Nagano, by means of X-ray fluorescence spectrometer in order to determine the origin of obsidian. With regard to the old site of the Izumi Campus, we analyzed 240 pieces of obsidian stone tools, of which 213 pieces were determinable. The result indicated that, for the most part, the obsidian was from Hatajuku series of Hakone area and Nishi-Kirigamine series of Kirigamine area, both of which had about same quantity. As for the rest, few were from Kajiya and Kamitaga series of Hakone area and Takaharayama series of Takaharayama area. With respect to the Uenodaira Site, we analyzed 230 pieces of obsidian stone tools, of which 189 pieces were determinable. As the result, the obsidian from Nish-Kirigamine series of Kirigamine area accounts for 59 of them, followed by that from Wadatouge-Takayama series of Kirigamine area with 29% and that from Omegura series of Kirigamine area with 9%, respectively. Other sources include Tsumetayama-Mugikusatouge series of Kitayatsugatake area. Further investigation is required on this result, in order to consider comprehensively taking into account the location of the sites as well as the found condition of the obsidian tools, regarding both sites we studied here.
