According to the passage, one solution offered to stop the loss of population and industrial strength is to ----.

In post-tsunami Japan, the prime minister must decide
which towns and villages in Tohoku will be restored and
which won’t be. Much of rural Japan has been losing its
population and industrial strength for years.
Decentralizing power, which would require a revolution
in the central government, would help the process.
Japan has long been a top-down economy: government
bureaucrats make the decisions and allocate the tax
revenues; local leaders react accordingly. Those in
Tokyo working on revival plans are caught up in
paperwork and are too far away from the damaged
areas to grasp the complexities of life there. Japan’s
de-populated towns need to join forces and share
budgets – a move central government is too busy and
distracted to make. The biggest mistake would be for
Japan to try to recreate what existed before the March
10, 2011 tsunami. Despite what has been a lost year for
Japan, the nation still has an opportunity for the kind of
restructuring that does not come along often. It would
be a shame if Japan wasted it.
