This study is based on the comprehensive collection of geographical maps that show reclaimed-lands on Tokyo Bay Area constructed through the end of Edo period to today. It aims to figure out of factors that effected and determined the form of reclaimed-lands, and also to reflect the dynamism between factors and forms from the morphological viewpoint. The research reveals five ocean-topographical factors and three artificial. Observing the process in which reclaimed-land forms emerge out on the ocean surface, the study reveals a particular behavior between factors and those forms: ‘metamorphosis of factor' of topographical factors that causes ‘double delay effect', and it also provides a way of interpretation of forms as the structure of ‘mainstay form' and ‘pleats form'. The collection of maps includes several unrealized plans in past that prove the appropriate relationship between topographical factor and forms is critical even in our era with developed civil engineering.
