Not metaphorical ones. Workers spent nearly two decades -- from 1973 to 1992 -- shaving rock and earth from the wooded peaks northwest of Kobe, loading it onto a ten-mile underground conveyor belt, transferring it to barges, and dumping it two miles out into Osaka Bay. The result is a rectangular artificial island covering roughly 580 hectares in the harbor of one of Japan's most geographically constrained cities. Kobe is squeezed into a narrow coastal strip between the sea and the steep Rokko mountain range, and by the mid-twentieth century it had simply run out of room. The solution was not to build up but to build out, manufacturing new land from the old mountains that hemmed the city in.

A ten-mile underground conveyor belt -- an engineering feat in itself -- shuttled the excavated material down to the coast, where it ...
