Architects: Heatherwick Studio
- Year: 2023

Heatherwick Studio’s new district in the heart of Tokyo has been opened to the public by the Prime Minister of Japan. Named Azabudai Hills, the project is the culmination of a thirty-year revitalization initiative. The neighborhood spans across 2.4 hectares of accessible green space, and features various mixed-use activities, integrating the urban into nature.


When Kisho Kurokawa designed his now iconic Nakagin Capsule Tower in 1972, the structure was meant to represent the core principles of Metabolism, experimenting with ideas of growth and change borrowed from biological processes. The emerging style in postwar Japan aimed to create buildings and megastructures that emulate living organisms that can evolve, expand, contract, and adapt to their changing conditions. Following this concept, the Nakagin tower was composed of 140 identical cell-like capsule units, each individually bolted to the two central shafts. The capsules were intended to be replaced and upgraded every 25 years, allowing for flexibility and mutation. The innovation proved to be impractical, however. Almost 50 years after its construction, the tower was demolished, but not in its entirety. A total of 23 capsules were saved and removed from the building to be given a new life. Now, the capsules are scattered around the world, continuing to represent Metabolist ideals in unexpected ways.

The concept of a city can be viewed as a constantly evolving system where both architects and users contribute to its design and redesign. While its framework may start with planners or designers, the character of the urban fabric is ultimately shaped by the societies and generations that inhabit it. The question of "city authorship" often arises in the context of masterplan design. Can architects and urban planners determine the extent to which a city will evolve through its initial design? The answer is no. User authorship then acknowledges that city planning should not be approached like building design, where designers attempt to predict every aspect of shape, pattern, behavior, and culture. Instead, it recognizes the role that people play in shaping the urban fabric through their personal taste in architecture, the development of neighborhood personality, and ongoing redesign that contributes to the story and spirit of a place. These factors should be considered in the initial design by engaging ideas related to future expansion, adaptable infrastructure, and empowering citizens to contribute to the city's architecture, thus making the city design democratic. This article explores conceptual radical cities where designers embrace the ideas of user authorship and the constant evolution of ephemeral architecture.

Ennead Architects has been enlisted to redefine the campus of The American School in Japan (ASIJ) to align the international school’s academic mission with its environment. Currently defined by its aging and fragmented infrastructure, the campus is set to become a dynamic and innovative space, encouraging integrated learning, cohesion, and collaboration across age groups. Sustainability principles, along with the experience of Japanese heritage, also play an important role in the design of the master plan, which proposes a toolkit of solutions intended to help create a unified, sustainable and resilient campus.


OMA’S inaugural tower in Tokyo and Japan, designed by Shohei Shigematsu and OMA New York, the Toranomon Hills Station Tower, will open this fall, 2023. The inauguration of the Toranomon Hills Station Tower will mark a significant milestone in Mori Building's Toranomon Hills development, an emerging global business center, and urban hub. A multi-layered transportation node integrated into the tower will establish a new gateway linking Central Tokyo with the rest of the world.







In the following interview with Paul Tange, the chairman and senior principal architect at Tange Associates in Tokyo, we discussed the relationship with his famous architect-father Kenzo Tange (1913-2005; the most influential architect in postwar Japan and the winner of the 1987 Pritzker Prize), the fate of the house Tange senior built for his first family, the decision of joining his father’s practice right after graduation from Harvard, sharing his father’s design principles, and the vision behind his first independent built work – a 50-story Mode Gakuen Cocoon Tower in Tokyo, a vertical campus that can accommodate up to 10,000 students; the project won an international competition, in which 50 international architects participated.
