Country report

The new Strategic Energy Plan of Japan was revised in April 2014. The 2014 plan summarises mid- and long-term energy policy.

As a low-carbon and quasi-domestic energy source, nuclear power is positioned as an important baseload power source. Under the condition that the focus remains on safety, nuclear energy, with its low and stable operational costs, can contribute to the stability of the energy supply-demand structure and to the stability and efficiency of energy supply without greenhouse gas emissions.

On the premise that safety comes first and that every possible effort is being made to resolve people's concerns, judgement as to whether nuclear power plants meet the new regulatory requirements will be left to the Nuclear Regulation Authority (NRA). In the case that the NRA confirms conformity of nuclear power plants to the new regulatory requirements, the Japanese government will follow NRA judgement and proceed with the restart of nuclear power plants.

The Japanese government is taking thorough measures to minimise the risk of accidents considering the experience and lessons learnt from TEPCO's Fukushima Daiichi nuclear accident. In addition, in the case of an accident, the government will cope responsibly with the accident based on the related legislation.

Japan is also taking all necessary measures and promoting related R&D to ensure nuclear non-proliferation and strengthen nuclear security in light of international developments, including hosting the Nuclear Security Summit and adopting the revised Convention on the Physical Protection of Nuclear Material.
