This study tries to clear the changes of slope area landscape in the central part of Tokyo during Edo era to present. The slope area which hadn't been used became a residential section gradually caused by the increase in the population. Then, the space which was a boundary was lost between the heights and the low land And, three factors influence space formation in the slope area. They are the original geographical features, the particulars of the land use, the conditions of the land possession. Much is a slope at present though many stairways existed on the road in the Edo Period. And the stairways which have landscape based on the natural geographical features are being lost in the central Tokyo by the large-scale re-development.
