Fukushima Prefecture is not abandoned. The vast majority of the region, over 97% of its land area, is open to residents, businesses, and visitors. What most people picture when they think of “Fukushima” is actually a small exclusion zone surrounding the damaged Fukushima Daiichi nuclear power plant, and even parts of that zone have been steadily reopening since 2017. The reality is more nuanced than the ghost-town images suggest: some towns are bustling again, others are nearly empty, and a few remain off-limits.
What’s Still Restricted
The remaining evacuation zone covers about 371 square kilometers, roughly 2.7% of Fukushima Prefecture’s total area. This land falls within what the Japanese government calls “Difficult-to-Return Zones,” areas where radiation levels were highest after the 2011 disaster. These zones sit within a handful of municipalities closest to the damaged plant, including parts of Futaba, Okuma, Namie, Tomioka, Iitate, and Katsurao.
Since 2017, the government has been carving out sections of these restricted towns for reopening through a program called “Specified Zones for Reconstruction and Revitalization.” Each municipality submitted its own reconstruction plan, and the government approved them between 2017 and 2018. The result is a patchwork: within a single town like Okuma or Futaba, some neighborhoods are open while others remain fenced off with security checkpoints.
Who Has Come Back
Return rates vary enormously depending on how close a town was to the plant and how long residents were displaced. Kawauchi, a village where the evacuation order was lifted in 2012, saw more than 80% of its population return. That’s the success story. At the other end of the spectrum, Okuma, where residents weren’t allowed back until 2019, had a return rate of roughly 3% as of early 2021. Out of over 1,100 surveyed Okuma residents, just 38 had moved back home.
The gap makes sense when you consider what eight years of displacement does to a community. People who evacuated in 2011 rebuilt their lives elsewhere. Children enrolled in new schools. Adults found new jobs. Elderly residents moved closer to medical care in larger cities. Even when the government lifts an evacuation order and declares an area safe, the social infrastructure that makes a town livable, schools, shops, hospitals, neighbors, takes much longer to rebuild. For many former residents, there’s simply nothing practical to return to yet.
Radiation Levels Today
Ambient radiation across most of Fukushima Prefecture has dropped dramatically since the disaster. The average air dose rate has fallen to about 0.10 microsieverts per hour, roughly one-nineteenth of the level measured immediately after the earthquake. That puts it on par with background radiation in major cities around the world, including places that were never near a nuclear accident.
This decline comes from two factors: the natural decay of radioactive materials (particularly cesium, which loses half its radioactivity every 30 years) and extensive decontamination work that involved scraping topsoil, pressure-washing buildings, and removing contaminated debris across thousands of square kilometers. Inside the remaining exclusion zones, levels are still elevated, which is precisely why those areas haven’t been reopened.
The Power Plant Itself
The Fukushima Daiichi plant is very much an active work site, not an abandoned ruin. Decommissioning is a multi-decade project expected to continue until sometime between 2041 and 2051. In September 2024, workers began the long-awaited process of physically retrieving melted fuel debris from the damaged reactors, marking a major milestone in the cleanup timeline.
Spent fuel removal from the reactor buildings is partially complete. Units 3 and 4 have been fully cleared, while preparation work continues at Units 1 and 2, with total completion targeted by 2031. Thousands of workers report to the site daily for decontamination, water treatment, and structural reinforcement. The plant grounds are a controlled industrial zone, not a deserted wasteland.
New Industry in Former Ghost Towns
Some of the most interesting developments are happening in towns that were completely evacuated. In Namie, one of the hardest-hit communities, the Fukushima Hydrogen Energy Research Field now operates a 10-megawatt green hydrogen production facility powered by renewable energy. It’s a collaboration between Japan’s national energy development organization, Toshiba, Tohoku Electric Power, and the industrial gas company Iwatani. The project was deliberately placed in the disaster zone as a symbol of reinvention, turning former farmland into a testing ground for clean energy technology.
The Japanese government has invested heavily in positioning the Fukushima coast as a hub for renewable energy and advanced research, partly to create economic reasons for people and businesses to move into areas that lost their original industries.
Tourism in the Disaster Zone
Visitors can and do travel to parts of the former exclusion zone. Fukushima Prefecture runs a program called “Hope Tourism,” offering guided educational tours through recovering communities. Originally designed for domestic travelers, the program drew over 9,000 participants in 2022, mostly Japanese high school students on school trips. An international component launched more recently, with a university ambassadors program that has brought 226 students from 16 universities across 8 countries as of late 2023.
For communities in the Futaba region, this kind of tourism is entirely new. International visitors were essentially nonexistent before the disaster. Now the prefecture is training interpretation guides and working to offer commercial tours for foreign travelers, using tourism as a way to counter the lingering reputation that the entire area is dangerous and deserted.
The Bigger Picture
Fukushima Prefecture is roughly the size of Connecticut. It includes mountain ranges, ski resorts, rice paddies, cities with tens of thousands of residents, and a long Pacific coastline. The disaster zone is a small fraction of this land. Even within the affected municipalities, life is returning in uneven but measurable ways: new housing developments, reopened train stations, research facilities, and memorial sites that draw visitors year-round.
The honest answer is that a small part of Fukushima is still functionally abandoned, with empty streets, overgrown lots, and buildings frozen in 2011. But the prefecture as a whole is not only inhabited, it’s actively reinventing portions of the disaster zone for purposes that didn’t exist before the accident. Whether those efforts will fully succeed depends on whether enough people choose to build lives there again, and that question is still playing out, one returning family at a time.
