The government plans to use state funds to finance the radiation cleanup in the areas most seriously contaminated by the Fukushima disaster in 2011, government sources said Friday.

It is the first plan to decontaminate the "difficult to return to" zones, including a large portion of the two towns hosting the crippled Fukushima No. 1 nuclear power plant and parts of other nearby municipalities in the prefecture.

The move is intended to expedite the cleanup process but may draw criticism because it will effectively reduce the financial burden on Tokyo Electric Power Company Holdings Inc., the utility responsible for the world's worst nuclear crisis since Chernobyl.
