The March 2011 meltdown at the Fukushima No. 1 nuclear power plant caused serious damage to forests in the surrounding areas. Even now, 11 years after the accident, little has been done to decontaminate them.

In some areas, projects are underway to restore the satoyama, areas of mountain forest maintained by residents of adjacent communities, but the airborne radiation levels in those areas are still not low enough that children can safely enter, according to a local community leader.

One such area is the Yamakiya district in the town of Kawamata, Fukushima Prefecture. Walking trails in the Daini Oyako no Mori forest are covered by snow, and sunny slopes are lined with zelkova trees.
