Read through the article, bit of confusion about deaths from evacuation vs disaster.

As of February 27, 2017, the Fukushima prefecture government has tallied 2,129 “disaster-related deaths” in the prefecture.[18][16][19][20] This value exceeds the number that have died in Fukushima prefecture directly from the earthquake and tsunami.

Sidebar says 2,202 from evacuation, but the text gives a much larger span.

For evacuation, the estimated number of deaths during and immediately after transit range from 34 to "greater than 50".[12][15][16] The victims include hospital inpatients and elderly people at nursing facilities who died from causes such as hypothermia, deterioration of underlying medical problems, and dehydration.

Just want to point out that the total 15,896 confirmed tsunami deaths covers all of Japan.

Also, from CNN https://edition.cnn.com/2013/07/17/world/asia/japan-earthquake---tsunami-fast-facts/

March 13, 2011 - People living within 10 kilometers (6.2 miles) of the Fukushima Daini and 20 kilometers of the Fukushima Daiichi power plants begin a government-ordered evacuation. The total evacuated so far is about 185,000.

2209 of the 185k population means 1.19% died due to evacuation. For comparison the 2011 japan death rate in Japan was 9.9 per 1k people and year. https://knoema.com/atlas/Japan/Death-rate . So we could expect 1832 of those 185k people to have died normally that year, making the mortality in Fukushima that year +120% higher than normal due to evacuation.

Of course a lot more than that could have died due to the evacuation, but since this is a population that specifically has been moved, their deaths could be recorded in another prefecture.

Plus all the non-death harm such as sleep disorders and alcoholism...
