The object of this paper is to consider the existing farm houses and the prosperity and decline of the Buntou style (unfloored part is separated from main farm houses) farm houses. At the Utsunomia district, about the biginning of the eighteenth century, 20-40 % of Buntou style houses had been lived by the upper classes in the village, but the end of the ninteenth century, they had not been found. Z-style (the ridge of a roof indicates character of the Z) of the farm houses had developed from the Buntou style and it had been already made up at the beginning of the eighteenth century. After that period, Z-style of the farm houses still has been built by a few upper classes.
