Six years ago, the triple disaster – earthquake, tsunami and meltdown at the Fukushima Daiichi power plant – took the lives of almost 20,000 people and displaced more than 160,000 people from their homes. More than 80,000 people are still living in temporary accommodation.

The disaster had an enormous impact on all members of the affected communities, but to this day it is women and children who "have borne the brunt of human rights violations resulting from it," according to a report by Greenpeace.

While some injustices faced by women and children were caused by policy failures in the immediate aftermath of the disaster, other women's and children's rights violations are a direct result of the current government's plans to resettle residents to "heavily contaminated ares in Fukushima," says Greenpeace.

In an effort to get back to normality as quickly as possible, the Japanese government is set to lift evacuation orders at the end of March and allow evacuated residents to return to areas close to the Fukushima power plant.

Greenpeace warned, however, that radiation levels are still dangerously high and called on the government not to "pressure" residents to return to their contaminated homes, under threat of losing financial support. A year after an area is declared safe, the government will stop paying compensation to evacuees.

In March, Japan will also cut housing support for people who decided to move out although they were not under a government evacuation order.

"Cutting off housing support for self-evacuees threatens more than 10,000 households, potentially forcing many people back to contaminated areas against their will," says Kendra Ulrich, Global Energy Campaigner with Greenpeace Japan. Ending compensation payments "even though radiation levels far exceed the long-term targets in many areas [...] amounts to economic coercion and is a deliberate violation of the law and survivors’ human rights."

"Atomic divorce"

The resettlement plans create a dilemma for those who refuse to go back to their former homes but are dependent on financial support, especially single mums. After the disaster, a lot of women separated from or even divorced their husbands, who chose to stay in contaminated regions because of their work, and evacuated with their children.

There are no official numbers on how many families split as a result of the disaster. But the phenomenon is common enough to have a name, "genpatsu rikon" – literally meaning "atomic divorce".

These mothers evacuated with their children from Fukushima prefecture.

Mothers are now faced with the choice between losing housing support or moving back to unsafe areas. In order to speed up the return of evacuees, the government decontaminated corridors and islands instead of entire areas, effectivley creating "an invisible, open-air prison for citizens to return to," says Greenpeace.

Decontaminated zones often consist of 20 meter strips along roads, around houses and agricultural fields. This poses a health threat as the returnees would be surrounded by contamination.

Mothers are worried about their health and the development of their children. Noriko Kubota, a professor of clinical psychology at Iwaki Meisei University, believes that living in "safe zones" could have a long-lasting negative impact on kids.

"If children need to stay inside and cannot run around outside freely, that would impact their psychological development, more specifically their skills of interacting with each other and controlling their emotions among others," Kubota told DW.

Mothers sue government

Women are, however, not only silent victims in this disaster. Thousands of mothers have together filed lawsuits against the Japanese government to fight for the continuation of housing support and fair compensation. They also demand accountability for the disaster from the government and Tokyo Electric Power Co. (TEPCO), the company running the Fukushima Daiichi plant.

Ms Horie is sueing the government for fair compensation.

"I never imagined becoming a plaintiff myself. I'm going to court now for my children and for the next generation," Ms Horie told Greenpeace. She moved with her children from Fukushima to Kyoto, where she filed a class action suit together with other mums. "Back then, they said on TV that the accident wouldn't affect our health immediately, but it might affect my kids in the future. That's why I decided to evacuate."

Women who left contaminated areas have been "labeled as neurotic or irrational," says Greenpeace. Their concerns were dismissed both by their partners and the government. The lawsuit is not only about financial compensation but also for moral satisfaction.

"I want to stand in court, knowing that I am right to evacuate my child," says Ms Sonoda, who moved with her child from Fukushima to England. "We are right.”
