As underground sun
Deep below Tokyo's financial district, the Pasona Group, an international employment agency, has flipped the switch on a stunning experiment in urban agriculture. The company converted a bank vault in the subbasement of its headquarters into a series of supersized greenhouses, all bathed in the glow of computer-controlled grow lamps. Pasona O2, as the project is known, was launched to pique interest in new methods of farming—and to generate future employment opportunities in an island nation largely dependent on others for its food. For now the subterranean gardens are still more a showpiece than a serious producer, since they yield only 132 pounds of rice a year.
