"If you started looking at every single person, the project wouldn't move forward. You wouldn't get a tenth of the people you need," said Yukio Suganuma, president of Aisogo Service, a construction company that was hired in 2012 to clean up radioactive fallout from streets in the town of Tamura.
The sprawl of small firms working in Fukushima is an unintended consequence of Japan's legacy of tight labor-market regulations combined with the aging population's deepening shortage of workers. Japan's construction companies cannot afford to keep a large payroll and dispatching temporary workers to construction sites is prohibited. As a result, smaller firms step into the gap, promising workers in exchange for a cut of their wages.
Below these official subcontractors, a shadowy network of gangsters and illegal brokers who hire homeless men has also become active in Fukushima. Ministry of Environment contracts in the most radioactive areas of Fukushima prefecture are particularly lucrative because the government pays an additional $100 in hazard allowance per day for each worker.
Takayoshi Igarashi, a lawyer and professor at Hosei University, said the initial rush to find companies for decontamination was understandable in the immediate aftermath of the disaster when the priority was emergency response. But he said the government now needs to tighten its scrutiny to prevent a range of abuses, including bid rigging.
"There are many unknown entities getting involved in decontamination projects," said Igarashi, a former advisor to ex-Prime Minister Naoto Kan. "There needs to be a thorough check on what companies are working on what, and when. I think it's probably completely lawless if the top contractors are not thoroughly checking."
The Ministry of Environment announced on Thursday that work on the most contaminated sites would take two to three years longer than the original March 2014 deadline. That means many of the more than 60,000 who lived in the area before the disaster will remain unable to return home until six years after the disaster.
Earlier this month, Abe, who pledged his government would "take full responsibility for the rebirth of Fukushima" boosted the budget for decontamination to $35 billion, including funds to create a facility to store radioactive soil and other waste near the wrecked nuclear plant.
