TOKYO (AP) — A Japanese governor said Wednesday the country should not restart any nuclear plants until the cause of the Fukushima meltdown is fully understood and nearby communities have emergency plans that can effectively respond to another major accident.

Hirohiko Izumida, governor of central Niigata prefecture — home to the seven-reactor Kashiwazaki-Kariwa plant — said regulators look at equipment but don’t evaluate local evacuation plans.
