The Tohoku region, which has three of the prefectures hit hardest by the 11 March 2011 disasters, saw 129,385 people leave.

The prefectures affected are of Iwate, Miyagi and Fukushima.  Fukushima had the most people leave; 31,381.

Believe it or not, people did actually move into the region.  88,159 people moved in, making the net loss of population 40,000. According to Japan’s Internal Affairs Ministry, that’s still the biggest decline in population, in that region, since 1970.
