The aim of this study is finding the critical gradient of housing plot, for the purpose of defining the area of settlement in Jomon-preriod. In this paper, we find the relation between the gradient of site and housing location; tanθ>1/4・・・few or no house, 1/4≧tanθ≧1/6・・・a few house, 1/6>tanθ・・・suitable for housing.
