The purpose of this report is to reveal the utilization of woods, which were used for materials of pit dwellings from the Epi-Jomon culture (1 st century) to Satsumon culture (13 th century). I analyzed and concentrated on three points concerning the charred woods excavated at sites in Hokkaido. First, I analyzed the situations of wood materials that were construed as roof structure by investigating the distribution patterns of excavated woods in pit dwellings at several sites. In Hokkaido, some houses were discovered to be burned down, which is a sign of abandonment, and in those situations charred woods were found in the soil. Second, I made wood identifications by scanning an electron microscope over the charred woods excavated at pit dwellings and examining the results. Finally, I compared the results of the wood identifications with vegetation around each site, which has been suggested in previous analyses of geomorphological processes and pollen analyses. I concluded that the utilization of woods to build pit dwellings changed from diverse to uniformed between the Epi-Jomon culture and Satsumon culture, and that this was mainly due to the selections from surrounding environments.
