ABSTRACT
Kenzo Tange's proposal for the "structural reorganization" of Tokyo can be considered an attempt to control urban sprawl on a regional scale, after the setback of postwar governmental initiatives. From September of 1959 to February of 1960, Tange was invited to be a visiting professor at Massachusetts Institute of Technology (MIT). 'Bay Projects' by Tange around the turn of the 1950s and 1960s—namely, MIT Boston Harbor Project, 1959 and A Plan for Tokyo, 1960—are representatives of the Megastructure on an urban scale built out into the sea. Tange himself was not an official member of the Metabolism group; his 'Bay Projects' influenced Megastructure approaches of Metabolism through a three-dimensional circulation system that served as linkage between the individual buildings and the city. The MIT Boston Harbor Project, 1959 is sited on reclaimed islands over Boston Bay. A Plan for Tokyo, 1960 is the most well-known Megastructure proposal by Tange, which had incontrovertible influence on other Megastructure projects of Metabolism.
