Overview

The Nakagin Capsule Tower opened in Tokyo in 1972 with 140 prefabricated rooms on two central cores.

Kisho Kurokawa designed each compact capsule for one occupant, with a circular window giving the building its unmistakable appearance. The units were initially promoted to commuting businesspeople needing a small city base.

Residents later adapted capsules as homes, offices, studios and other spaces. The tower was dismantled in 2022, but 23 capsules were rescued.

Why It Mattered

The tower made the Japanese Metabolist idea of replaceable, adaptable architecture visible at full scale. Its capsules were never renewed as intended, but their varied later uses gave the building a more complex life than the original system promised.

Prefabricated Structure

• The building contained 140 capsules prefabricated away from the site.
• The capsules were attached to two structural cores made from concrete and steel.

Changing Uses

• The units were first promoted as compact dwellings for commuting businesspeople.
• Residents later adapted capsules as homes, offices, studios, libraries, galleries and other spaces.

Dismantling and Survival

• The tower was dismantled between April and October 2022.
• Twenty-three capsules were rescued.
• MoMA's capsule A1305 was restored in 2022–2023.
