Japan restarts first nuclear power plant since Fukushima
Japan has restarted its first nuclear reactor under new safety rules following the 2011 Fukushima disaster, sparked by a tsunami and earthquake.
Since then, some people in Japan have opposed the return to nuclear energy.
But operators say the reactor has passed rigorous new safety checks - and Kyushu Electric Power restarted the number one reactor at its Sendai plant on Tuesday morning.
