Five years after the meltdowns at the Fukushima Daiichi nuclear plant, Japan still faces another four decades or more of cleanup. One of many problems is what to do with the massive amount of contaminated soil from the site–which is now in a growing pile of bags stacked on former farms in Fukushima.

A new photo series from Japan-based photographer James Whitlow Delano documents the sprawl of nuclear waste.

As of 2015, the government reported that there were more than 9 million bags in the prefecture. Some of it will be moved inside the no-entry zone next to the nuclear plant, which is so radioactive that the government has given up on decontamination for the moment. But Japan is also sending radioactive waste to other parts of the country.

“The Japanese government decided early on in the decontamination process that all prefectures in Japan should share the burden of storing radioactive waste with Fukushima Prefecture,” says Delano, who has been photographing the disaster since it happened in 2011. “This resulted in firm pushback by communities in other prefectures that are adjacent to sites that were selected.”

They have reason to be concerned: In September of 2015, when there were floods in Nikko, Japan, hundreds of bags of radioactive soil were washed into the local river.

Even in Fukushima itself, in villages where many residents may not be able to return for a decade or more, no one wants a radioactive dump next to their former homes. The dumps are supposed to be temporary and moved in 30 years, but people are skeptical that will happen. “They feel like the presence of the site will be like the last nail in the coffin for their communities,” he says. “So, no one wants this contaminated soil.”

In some areas, a few people have started moving back. “When I used to sneak inside the old 20-kilometer-radius nuclear no-entry zone, I would enter a neighborhood in Minami Soma that was half inside the zone and half outside and hop the barrier to document the absence of humanity,” says Delano. “About one and a half years after the earthquake and tsunami, the no-entry zone was readjusted to reflect the actual radiation levels, instead of being an arbitrary 20-kilometer radius. That meant that the whole neighborhood would be decontaminated and prepared for families to return, if they wanted to do so.”
