Japan is densely populated. The Kantô
and Nôbi plains are home to Japan's largest cities and over half of
the nation's people. Tokyo is at the heart of the Kantô Plain. Nagoya
is in the Nôbi Plain.
One way to comprehend just how crowded
Japan's big cities can be is to unfold a couple sheets of newspaper and
lay them on the floor. Adjust them so they occupy about a square meter
of space. Then stand in the middle of the newspaper and invite four
friends to join you on the newspaper. During rush hour, the
Tokyo-Yokohama subway system has about five people per square meter.
