THIS PAPER AIMS TO CLARIFY THE PROCESS BY WHICH TOKYO'S BUILT-UP AREA CHANGES. THE METHOD OF IMAGE PROCESSING IS APPLIED, USING 1:10,000 MAPS OF MEIJI, TAISHO AND SHOWA ERAS. FIRST, THE PROCESS OF MAKING IMAGE DATA IS EXPLAINED. SECOND, "FORM ANALYSIS" WAS APPLIED TO BACK UP GENERAL KNOWLEDGE, SUCH AS THE EXPANSION OF TOKYO IN A WESTERLY DIRECTION. THIRD, LOOKING AT "GRAINS", DEFINED AS THE MIDDLE GROUND BETWEEN CITY PLAN (LARGE) AND BUILT FORM (SMALL), THIS PAPER CONCLUDES THAT URBAN GROWTH, CONSISTS OF A PARALLEL INCREASE IN BOTH THE NUMBER AND SIZE OF "GRAINS".
