The Japanese government should scrap distinctions between "mandatory" and "voluntary" evacuees from the 2011 Fukushima nuclear disaster and take a rights-based approach to ongoing support for those still displaced by its effects, a U.N. human rights expert said Friday.Cecilia Jimenez-Damary, the U.N. special rapporteur on the human rights of internally displaced persons, made the calls as the government and Tokyo Electric Power Company Holdings Inc., the operator of the crippled Fukushima nuclear power plant, have been exposed to numerous lawsuits from voluntary evacuees and those who returned to their former communities.The distinctions have had "particularly severe impacts on those in poverty, those with no livelihoods, the elderly and persons with disabilities," Jimenez-Damary said at a press conference to announce the preliminary findings from her Sept. 26 to Oct. 7 official visit to Japan.A human rights lawyer with decades of experience, Jimenez-Damary told reporters that a desire to return did not define evacuees and described conversations she had with displaced people on her visit to Japan and elsewhere, saying, "When I ask if they want to return, they say yes, but when I ask can you return, they say we cannot."Jimenez-Damary said the issue "needs to be resolved because it is not clear how many are in evacuation" when asked whether the government's estimate of the number of internally displaced people reflects the reality."
