The Nakagin Capsule Tower building in Tokyo, Japan was Metabolism architecture designed by Kisho Kurokawa in 1972 to showcase sustainability to the world—functionality, durability, and design of expandable compact spaces. It was demolished in 2022, but we made one of the capsules into a moving vehicle in February 2023 because it was a historical icon of Japan's postwar architecture. The capsule trailer, with its lightweight and restored interior, attracted people. It still challenges us to question our values of sustainability and remote work.
