Three and a half years after Tokyo Electric Power Co.'s crippled Fukushima No. 1 nuclear power station spewed massive amounts of radioactive materials into the air and water, decontamination work in Fukushima Prefecture has yet to draw to an end.

The government initially hoped to complete the decontamination by the end of last March, but the process continues to lag far behind, prompting the government to push back the goal by three years to 2017.

Due to the slow progress, huge bags filled with contaminated soil can still be seen piled up at hundreds of temporary storage sites across the prefecture, and many residents are in limbo, unable to make up their minds about whether to return home in the near future or to relocate for good.
