The new Basic Energy Plan endorsed last week that underscores the need to continue to use nuclear power, marking an important milestone in energy policy since the 2011 Fukushima No. 1 nuclear plant disaster started.

But the content of the plan still appears open to debate. Specifics of the country's future energy composition are lacking and in some aspects the plan can be seen as not sufficiently reflecting the lessons learned from the Fukushima crisis.

"Based on this policy, the government will move on to discuss the details . . . such as those on energy conservation, renewable energy and nuclear power," Minister of Economy, Trade and Industry Toshimitsu Motegi told reporters Friday.
