36. It is pretty darn dense

Roughly 10,000 people per square mile in the metro area, by my calculations. Of course, the 23 wards/boroughs that make up what is considered the city of Tokyo are much more densely packed-- 9 million people living in 623 square kilometers (240 square miles)! The 13 million figure you cited is the population of what they call here the Tokyo Metropolis-- or, Tokyo State, if you will (like New York City and New York State)-- 13 million people living in 845 square miles (including the 23 boroughs). There are millions more on the west side of Tokyo (Yokohama, Kawasaki, etc), on the north (Saitama, Urawa, etc), on the northeast (Matsudo, Kashiwa), and along Tokyo Bay. All very crowded, high-density areas. My city roughly 40 miles NE of Tokyo (considered to be on the edge of the metro area by some interpretations) has a lower population density of "only" about 1000 per square mile, and it's a little less compact than a neighboring city.

Trying to evacuate the area between Dai-ichi (excluding the exclusion zone, which is already evacuated) and Tokyo would be a logistical nightmare. And that's not even counting the people who are living on the other side of Dai-ichi.
