A movement in Japanese architecture of the 1960s reflecting the belief that cities could be designed according to organic paradigms. Metabolist architects hoped that the use of biological processes as models would give them efficient ways to deal with the rapid growth and technological progress of societies all over the world. Their design philosophy involved gigantic buildings. This monumental scale reflected operations they also saw at work in contemporary urban growth; their buildings were to become nodes in the organic fabric of the rapidly growing city.
