Tama New Town Development Plan based upon the natural topography that was proposed in 1965 and abandoned afterwards was examined in this study in terms of 1 relationship between structure of the natural topography and land use pattern, 2 allocation of open space, pedestrian ways and their networking system, and 3 several noted aspects of functional system to sustain the overall space organization in the developed area. A comparative study with the realized development plan, which required higher amount of landform transformation, revealed some significant contemporary meanings of the plan based upon the natural topography as follows. The most basic structure of the natural topography in hilly area represented by ridgelines and valley areas was applied to articulate numerous land use units in the developed area, to create a network of open spaces and pedestrian ways rich in experience of natural environment, and to function as a physical elements that realize an optimum organization of residential districts and other facilities. In this sense, the area would have been preserving substantial resources for the future restoration based on the infrastructure of natural environment.
