Utilities lack funds to decommission reactors; consumers may foot the bill
Under lax oversight by the industry ministry, electric power companies have failed to set aside enough money to decommission their nuclear reactors, creating a 170-billion-yen ($1.71-billion) shortfall that consumers may be forced to cover.

According to an investigation by The Asahi Shimbun, decommissioning funds fell short of the targets for 34 of the nation’s 50 nuclear reactors as of March based on the idea that reactors should be mothballed after 40 years in operation.
