Japan cleared the way on Wednesday for a resumption of nuclear power, four years after the world's worst atomic disaster in more than two decades led to the shutdown of all the country's reactors and fueled public opposition to the industry.

Regulators said Kyushu Electric Power Co.'s two-reactor Sendai nuclear plant had cleared safety hurdles introduced after the triple meltdowns at Tepco's Fukushima No. 1 plant in 2011.

The Sendai plant, in Kagoshima Prefecture, still needs to go through operational checks before a restart but these are expected to be completed without major hitches.
