Built in the Ginza area of Tokyo, a total of 140 capsules are stacked and rotated at varying angles around a central core, standing 14-stories high. The technology developed by Kurokawa allowed each unit to be installed to the concrete core with only 4 high-tension bolts, which keeps the units replaceable. Each capsule measures 4 x 2.5 meters, permitting enough room for one person to live comfortably. The interior space of each module can be manipulated by connecting the capsule to other capsules.
All pieces of the pods were manufactured in a factory in Shiga Prefecture then transported to the site by truck. The pre-assembled interior features a circular window, built-in bed and bathroom, and is furnished with a TV, radio and alarm clock. Hoisted by a crane, the capsules were inserted in the shipping containers by use of a crane, and then fastened to the concrete core shaft.
