Even though the tens of thousands of evacuees from the March 2011 earthquake, tsunami and ensuing Fukushima nuclear disaster are still living in temporary housing, many others have moved on, making virtual ghost towns out of once busy communities.

As of the end of November, 19,373 people were still in 16,403 temporary housing units in Fukushima, down from the peak of 33,016 people in July 2012. The disaster rescue law stipulates that residents can live in temporary housing for up to two years, but the prefecture extended that to March 2017.

But as more people move into new public housing or elsewhere, some 38 percent of the temporary housing units in Fukushima were vacant as of the end of November, up from 17 percent at the same time in 2013.
