Japan has restarted its first nuclear reactor under new safety rules following the 2011 Fukushima disaster. All Japan’s nuclear plants were gradually shut down after a series of meltdowns at the Fukushima plant sparked by the tsunami and earthquake. But after passing stringent new safety tests, Kyushu Electric Power restarted the number one reactor at its Sendai plant on Tuesday morning.

However there is still strong public unease about a return to nuclear power. Protests have been taking place outside the Sendai plant and at Prime Minister Shinzo Abe’s residence in Tokyo, about 1,000 km away.
