Land-use policy in the country was skewed by the inordinate power of the small holders of farmland, and it was not unusual to see a small patch of land in the midst of a suburban setting allocated to the growing of a quarter hectare of vegetables. Small already—the entire nation was about the size of California, and populated with roughly half the people of the United States—their country was further crowded by the fact that little of the land was arable, and since arable land also tended to be land on which people could more easily live, the major part of the population was further concentrated into a handful of large, dense cities, where real-estate prices became more precious still. The remarkable result of these seemingly ordinary facts was that the commercial real estate in the city of Tokyo alone had a higher "book" value than that of all the land in America's forty-eight contiguous states. More remarkably still, this absurd fiction was accepted by everyone as though it made sense, when in fact it was every bit as madly artificial as the Dutch Tulip Mania of the seventeenth century.
