living space. Towards the Group Form Maki and Otaka's essay on Group Form placed less emphasis on the megastructures of some of the other Metabolists and focused instead on a more flexible form of urban planning that could better accommodate rapid and unpredictable requirements of the city. Otaka had first thought about the relationship between infrastructure and architecture in his 1949 graduation thesis and he continued to explore ideas about "artificial ground" during his work at Maekawa's office. Likewise, during his travels abroad, Maki was impressed with the grouping and forms of vernacular buildings. The project they included to illustrate their ideas was a scheme for the redevelopment of Shinjuku station which included retail, offices and entertainment on an artificial ground over the station.

Material and Man Kawazoe contributed a brief essay entitled I want to be a sea-shell, I want to be a mold, I want to be a spirit. The essay reflected Japan's cultural anguish after the Second World War and proposed the unity of man and nature.

The design was a radical plan for the reorganization and expansion of the capital in order to cater for a population beyond 10 million. The design was for a linear city that used a series of nine-kilometre modules that stretched 80 km across Tokyo Bay from Ikebukuro in the north west to Kisarazu in the south east. The perimeter of each of the modules was organised into three levels of looping highways, as Tange was adamant that an efficient communication system would be the key to modern living. The modules themselves were organised into building zones and transport hubs and included office, government administration and retail districts as well as a new Tokyo train station and highway links to other parts of Tokyo. Residential areas were to be accommodated on parallel streets that ran perpendicular to the main linear axis and people would build their own houses within giant A-frame structures. The project was designed by Tange and other members of his studio at Tokyo University, including Kurokawa and Arata Isozaki. Originally it was intended to publish the
