A Plan for Tokyo, 1960
Core idea
A linear civic spine of interlocking loops extended across Tokyo Bay for growth.
Why it matters
The scheme that launched the Metabolist megastructure decade.
Description
A Plan for Tokyo 1960 is an unbuilt proposal by Kenzō Tange and his studio, presented at the World Design Conference in Tokyo. To relieve the congested radial city, it proposed abandoning the existing centre and extending a linear civic axis some eighteen kilometres across Tokyo Bay. The spine carries a multi-level transport system from which interlocking loops of development branch out, with large megastructural frames housing offices and government and pilotis-raised residential A-frames over the water, intended for around five million people. The plan replaces the centripetal, radial city with an open-ended linear structure that can grow incrementally, organising movement, communication and building into a single hierarchical system.
Significance
Tange's plan reconceived the metropolis as an extensible linear structure rather than a bounded radial form, directly addressing post-war Tokyo's explosive growth. Its hierarchy of fixed infrastructure and changeable building units provided the founding image of Metabolism and shaped a decade of megastructure thinking in Japan and abroad. Though unbuilt, it influenced later artificial-island and bay-development proposals and remains a landmark of twentieth-century urban theory.
What became of it
The plan was never executed, remaining a paper project, but it became a foundational work of the Metabolist movement and shaped Tange's later career.
Critique
Its monumental scale and reliance on a single megastructural spine made it economically and politically unrealisable.
