THE POLITICAL, ECONOMIC, AND SOCIAL MODERNIZATION HAD OCCURRED AT THE TRANSITION PERIOD FROM EDO ERA TO MEIJI ERA IN JAPAN. IT IS THE PURPOSE OF THIS THESIS TO CONSIDER HOW THAT MODERNIZATION HAD EFFECT ON SPATIAL CHANGE OF URBAN OPENSPACE OF EDO TO TOKYO. OUKAN OF EDO, WHICH SPATIALLY CORRESPONDS TO PRESENT ROAD, HAD WORKED AS AMUSEMENT QUARTERS OR SOCIAL COMMUNICATION PLACES. BECAUSE OF THE CHANGE OF LANDOWNING-SYSTEM FROM FEUDALISM TO MODERNISM AND THE INTRODUCTION OF VEHICLES FROM WESTERN EUROPE AT MEIJI ERA, THE CHARACTER OF OUKAN HAD ALTERED TO A ROAD WHICH IS MAINLY FOR TRANSPORTATION UNDER OFFICIAL MANAGEMENT. AND SOME FUNCTION ELIMINATED FROM OUKAN HAD BEEN ALLOTTED FOR THE PUBLIC PARKS ALSO UNDER OFFICIAL MANAGEMENT. IT COULD BE CONCLUDED THAT THE PUBLIC PARKS HAD EMERGED AS VERY MODERN SPATIAL APPARATUS.
