18 No recovery without decontamination To be born in Fukushima, grow up in Fukushima, work in Fukushima, get married in Fukushima, have children in Fukushima, raise children in Fukushima, see the faces of my grandchildren, see the faces of my great grandchildren, and spend the last days of life in Fukushima. This is my dream. From A Message from Fukushima at the opening ceremony of the 35th All Japan High School Integrated Cultural Festival. To restore the true sky of Fukushima as soon as possible, we are determined to continue to face the many challenges ahead of us. 18
