Nobuo Abe was a senior manager, managing one of the design divisions on the construction of the Nakagin Capsule Tower. Since 1996, the tower was listed as an architectural heritage by DoCoMoMo. However, in 2007 the residents voted to tear the tower down and build a new 14-story tower. In 2010, some of the remaining habitable pods were converted for use as budget hotel rooms. As of 2017, many capsules had been renovated and were being used as residential and office spaces, while short-stay renting such as Airbnb or other lodging provisions had been banned by the administration of the building. The tower was demolished in April of 2022. Hillside Terrace, Tokyo After the World Design Conference Maki began to distance himself from Metabolist movement, although his studies in Group Form continued to be of interest to the Metabolists. In 1964 he published a booklet entitled Investigations in Collective Form in which he investigated three urban forms: Compositional-form, Megastructure and Group Form.

It includes residential, office and cultural buildings as well as the Royal Danish Embassy and is situated on both sides of Kyū-Yamate avenue in the Daikanyama district of Tokyo. The execution of the designs evolves through the phases with exterior forms becoming more independent of the interior functions and new materials being employed. For example, the first phase has a raised pedestrian deck that gives access to shops and a restaurant and this was designed to be extended in subsequent phases but the idea, along with the original master plan, was discarded in later phases. By the third phase Maki moved away from the Modernist maxim of form follows function and started to design the building exteriors to better match the immediate environment. The project acted as a catalyst to the redevelopment of the whole area around Daikanyama Station. Metabolism in context Metabolism developed during the post war period in a Japan that questioned its cultural identity. Initially the group had chosen the name Burnt Ash School to reflect the ruined state of firebombed Japanese cities and the opportunity they presented for radical re-building. Ideas of nuclear physics and biological growth were linked with Buddhist
