The building that was never meant to be an apartment house

In short: In 1972, Kisho Kurokawa unveiled a radical vision for Tokyo: a tower of 140 prefabricated capsules. It wasn't just a building; it was a prototype for a dynamic, adaptable city. Yet, despite its futuristic design, it faced a controversial end in 2022.

The Nakagin Capsule Tower was the definitive realization of Metabolism, an avant-garde Japanese architectural movement of the 1960s. Metabolism imagined cities and buildings as organic, evolving systems rather than static structures. In Tokyo's Ginza district, Kurokawa conceived the tower as a fluid arrangement of 140 individual capsules, which were manufactured elsewhere before being joined to two steel-and-concrete pillars. This modularity was intended to allow the building to adapt over time, reflecting a postwar techno-futurist vision of urban living.

The units demonstrated surprising flexibility, despite being initially sold to working professionals as tiny homes for travel. Throughout many years, these spaces were converted into various uses, such as galleries, libraries, tea rooms, art studios, dorm rooms, offices, and even DJ booths or second homes. Kurokawa even integrated traditional aesthetics into this high-tech vision, noting that the capsules' dimensions mirrored those of a traditional Japanese tea-room and that the building's asymmetry reflected a rejection of symmetry in Japanese architectural tradition.

Despite its cultural significance as the world's first example of capsule architecture, the tower suffered from years of deferred maintenance. Efforts to save it as a historic landmark were unsuccessful, leading to its controversial demolition in 2022. Today, its legacy is preserved through the restoration of capsule A1305, serving as a case study in how architecture can evolve beyond its original design to take on new roles and meanings.
