The second arithmetic is human. Before the disaster, Fukushima Prefecture was a lush, agricultural heartland—famous for peaches, rice, and sake. Post-meltdown, evacuation orders covered over 1,150 square kilometers. As of 2024, despite aggressive decontamination (scraping away entire topsoils and stuffing them into an endless labyrinth of black bags), roughly remain designated as “Difficult-to-Return” areas. Villages like Namie and Iitate are open for day trips, but the census tells the truth: only about 25% of the original evacuees have returned permanently. The rest have rebuilt lives in Tokyo, Saitama, or Chiba. They are no longer Fukushima citizens; they are diaspora. The prefecture’s population has dropped by over 150,000 people—roughly one quarter of its pre-2011 total.

However, for the people displaced and the environment altered forever, the fraction matters less than the reality: even a quarter of a nuclear catastrophe is a life-altering tragedy. They are no longer Fukushima citizens; they are diaspora
