The building was designed to be taken apart. We kept it whole, and lost it anyway.
Fifty-two years after the last welded module was hoisted onto its concrete spine in Ginza, the demountable idea remains the most stubbornly unfinished promise of postwar Japanese architecture.
The circular window is the size of a washing-machine door — 1.3 metres across, cast in a single dark disc, and, if you sit in the right chair, precisely wide enough to frame the Shuto Expressway sliding past at ear level. I spent four afternoons last winter inside a preserved capsule that had been trucked to a workshop north of Saitama, and what surprised me was not the smallness but the density: 10.6 square metres in which every fitting had been argued over, welded in, and, in principle, meant to be unbolted again.
02 — A spine, a socket, and 140 arguments about time
Two exposed concrete shafts held everything up. The capsules were the argument. Each one arrived complete from a factory in Shiga: bath, bed, tape deck, the porthole already glazed. Four high-tension bolts fixed the box to the core. In the specification drawings the intended lifespan of a capsule was twenty-five years; the tower itself, a hundred. Nobody agreed on who was supposed to pay for the swap, and so, quietly, nobody did.
