For 10 points, name this 1960s Japanese architectural movement whose name hints that it uses "organic" principles in the design of buildings.
In 2008, the group Atelier Bow-Wow released a manifesto stating that a "void" form of this movement can counteract the haphazard fashion of "single-family houses and small buildings." The original-language name for this movement literally means "replacing the old with the new" and was outlined after its first members gathered at the World Design Conference and learned about the ideas behind the Richards Medical Research Laboratories of Louis Kahn. An artist suggested that this movement's "changing requirements of the contemporary age" could be met by attaching "pods" to enormous cylinders, and putting them into the ocean to create a "Marine City." Though many of the founders of this movement were concerned with creating "megastructures," only a few buildings from this movement were realized, such as the still-standing Nakagin Capsule Tower.
