This paper tries to envisage the process and characteristics of transition in landscape caused by the changes of builtscape in the central area of Tokyo, Chiyoda Ward around the Imperial Palace, which has been a showcase of urban development projects of various kinds in order to initiate the wave of modernizing environment and landscape in Japanese cities. Salient evidences which influenced upon the spatial structure of landscape in this area were identified and chronologized. Will and Place or Value of Landscape Landscape changes along with the transition of society, and its shifts influence the mental value of places in turn. One of the substantial factors behind these changes is urban development projects. Artificial alterations of original topography with hills and rivers, constructions of buildings, roads and bridges, and transformations of landuse are all derived from urban development for the sake of environmental amelioration or economical efficiency. There has been, however, a huge untouchable zone in the midst. It has been regarded as sacred place, or rather void from planing point of view. It caused eccentricity of axial spaces. Characteristic landscapes of vista with explicit axial space, like the streets of Sotosakurada, Kudanzaka and Chiyoda in front of the Tokyo Station, are placed without systematic spatial context around the Imperial Palace. Dispersed open spaces increased anonymous places. Reversal of Dominance in Landscape The distribution of visual landmark was reversed from centripetal structure to centrifugal structure of urban space. In Edo Era, the castle tower, Tenshukaku, was a centripetal focus of this city. After it had been lost, new highrise buildings with western style occupied the position of dominant landmark in centirfugal way. Today, conservativeness about landscape in this area are now resulting in the rapid changes in its surrounding outer areas, which have large impacts on the outlines of landscapes in this area, exerting mental effects of supraliminal to subliminal significance. Place and Conformity or Coherence with Place Basic characteristics of segrigated zones which correspond to the previous landuse allotment in Edo Era are still remaining. For example, Banchou and koujimachi, residential zones for Daimyou and Hatamoto Samurai class, are now expensive residential zones, and Kanda, old highly inhabited zone, is active commercial business zone. This adherence to places sustain the value of places, or in other words, inheritance of identity or zonal traits. The mechanics of builtscape superimposed into landscape are underlayed by politics and economics on places, however, exerting implicit impacts upon human-environmental relations.
